In my textbook, the object ‘river’ was initialized to be ‘Mississippi’.

The replace method example:
river.replace("issipp", "our")

When I tried it, it didn’t work even when I added a semicolon at the end of the line.
My code:
String river = "Mississippi";
System.out.println(river);
String bigRiver = river.toUpperCase();
System.out.println(bigRiver);
bigRiver.replace("I", "E");
System.out.println(bigRiver);

Any help is appreciated!

Firstly in the replace method. It takes chars. So, try changing it to ‘I’ and ‘E’

but that is not the main problem.

the method bigRiver.replace(..) returns the changed string and it does not automatically update the string

So try changing it to bigRiver = bigRiver.replace(….).

So the code shld be like this.

public class Replace
{
public static void main(String [] args)
{
String river = "Mississippi";
System.out.println(river);
String bigRiver = river.toUpperCase();
System.out.println(bigRiver);
bigRiver = bigRiver.replace("I", "E");
System.out.println(bigRiver);
}
}

Yet, when I read "flood geology" evidences [I use that term as objectively as I respectfully can], they seem to associate any physical methods for monitoring flood-based water salt content changes, there seems to be presumption that the Noahic Flood brought a significant drop in salinity of the Gulf of Mexico, for example. (By the way, the cited "creation scientists" date the drop to about 11,500 years ago and call it "The Flood" but that date would correspond beautifully with the melting and retreat of the Wisconsin Glacier of the last great ice age, which surely would have sent an enormous cascade of melt water down through the Mississippi River system. So it looks like evidence for the Ice Ages is treated as evidence for a global flood.)
=======================================

Sorry for the confusion brought by some dropped words. I’m on an experimental connection.

I don’t really know. Here’s a thought to consider for your experiment: which had more volume of water? Was it the "firmament", or the "waters of the deep" (i.e. trapped in the earth). My experience in the oil & natural gas industry would tell me that if there were more waters of the deep, then the water would actually be very brackish and salinized because of what I have observed with the quality of produced water from the wells.

Which was not a reason that New England became the center of the American Industrial Revolution?

large numbers of swift-flowing rivers that could produce power

coastal trading ports on or near the Atlantic Ocean

access to Pennsylvania’s abundant supply of coal <—

climate that supported a large agricultural base

What helped spur the growth of American industry in the beginning of the nineteenth century?

increased federal support for entrepreneurs

trade agreements with France and England

trade embargoes and the War of 1812 <—

interstate commerce agreements between New England states

How did developing the system of roads in the early nineteenth century affect the economy?

It brought in additional federal revenues through tolls.

It made trade more attractive to foreign nations, especially England. <—

It helped the country transition from a subsistence economy to a market economy.

It caused a downturn in the economy because of road construction expenses.

What was an effect of Robert Fulton’s development of steamboat travel?

More people were willing to vacation along the waterways.

The cost of transporting goods became more expensive for farmers.

Westward expansion became much easier.

Trade along the Mississippi River began moving in both directions. <—

. How did the growth and development of railroads affect the American economy?

Railroads created a shortage of the coal that was used in fueling New England mills.

Railroads eliminated jobs for mule drivers, causing a recession in some areas.

Railroads made the rapid movement of produce and goods into many markets possible. <—

Railroads increased transportation expenses and strained the economy.

How had the American electorate changed by the election of 1828?

Thanks to the suffragette movement, women in some states were eligible to vote.

With landholding requirements still in place, fewer men were eligible to vote.

With landholding requirements eliminated, most white men were eligible to vote.

Property requirements for voting continued to keep African American men from voting.

I dont know the last one at all.

How had the American electorate changed by the election of 1828?

Changes in voting qualifications and participation, the election of Andrew Jackson, and the formation of the Democratic Party—due largely to the organizational skills of Martin Van Buren—all contributed to making the election of 1828 and Jackson’s presidency a watershed in the evolution of the American political system. The campaign of 1828 was a crucial event in a period that saw the development of a two-party system akin to our modern system, presidential electioneering bearing a closer resemblance to modern political campaigning, and the strengthening of the power of the executive branch

I’ve been reading a bit about the Mississippi and I’ll purposely leave out references and just tell you what I read. Three things stick out:
1. The Army Corps held winter water in upper river reservoirs to protect wildlife downstream (wetlands, etc.), apparently even after being warned that there would be well above normal spring run off.
2. A proposed system of damming rivers feeding the Mississippi was canceled several years ago due to environmental concerns (again delicate species, wetlands, etc.).
3. Many proposed increases to levees and spill ways were nixed due to environmental concerns.

In the environmental concerns, some bird called a piping plover seems to come up often. Regardless, I don’t know too much about this overall situation but it has me intrigued.

So, if the answer to the question is that man did have responsibility in this flooding, then what actions would you recommend for the future?
@antarcticice: You are surely not looking very hard: http://www.google.ca/search?source=ig&hl=en&rlz=1G1GGLQ_ENCA242&q=mississippi+flooding+climate+change&aq=f&aqi=g1g-b2&aql=&oq=

"For a start I can find no mention of a link between the flooding and AGW" You obviously have some very severely damaged filters.
@Andy: "…we should just nature takes it course and get rid of all levees along the rivers and let them be wild and free." I don’t think you’d win an election in very many states other than Colorado.

My thoughts is that it is all man’s fault. We put in place levees and other constrictions on the Mississippi and the rivers that feed into it for roughly 100 years. Now we are complaining that these same levees back up water into the incoming rivers causing flooding further back then nature would have allowed.

This is one of the reasons that we should just nature takes it course and get rid of all levees along the rivers and let them be wild and free.

2.) The Federal Government can create an " Agency For FLOOD CONTROL".
(measures the water going into cavern, verses measure of water coming out in Water Wells.)

3.) The cost of the project: payed by small revenue collected from export duties on produce.

4.) The benefits are enormous in employment, in management etc.

5.) How? The same machinary that tunnels through mountains, aim it down-slope to tavern.

6.) Where? Somewhere, north of De Moines, Iowa.

ADDITIONAL DETAILS:
Sorry, the problem is to large, for any other problem solving; That may, at its best, change hardly
nothing. Letting the problem continue, is already real, to fail is to serious of a consequence.
(No Attention to this problem, is like what happened to the banking, health, Insurance, etc. systems.) We Wait To Long, on politicians in Washington, whose motives are re-elections, and not the concern for the nation, The bread basket water, waits on no one, TERMINAL as is!
We the people need a Hero, can you make it, your priorty?
Perhaps, the Misouri River would lend itself better for this purpose. It lays closer to the underwater lake.
jemhash-Thank You for caring for good old USA’s Bread Basket to the world, from Australia. This large rivers get their source from winter snow & mountains, Devert 10% during Spring only. Jack A Much thanks to you, too.
I say,"Empty of water, water" not of the porous sponge, which I hope and expect to revert to spongging water again when refed. Even design a broad intake to facilitate the intake rate. Most grateful for your input, so far you’re the closest
to believeing and it shall be done. Where is that person, now, "Yes, We Can?" NASA, you’re not more interesting in solving Mars problems than in us are you? But you’re the one that found the cavern in the first place? Yes?

I don’t think tackling a problem like that would be as simple as you suggest. I understand the aquifer under the mid-west is more like a huge porous sponge than a cavern like Mammoth Cave in Kentucky. I guess It would be possible to drill reverse wells, build reservoirs and and channels from the rivers to pump water back into the aquifer. Good idea, but this is the first I’ve heard of the ‘empty’ aquifer. Maybe the government will do something before we have another dust bowl.
