Computer Programming Help [java]

Java computer programming help please! How do I create this program?

Write a program in a single class called DoubleLetters that does the following: The program should read in a single line of text from the keyboard. It should then print to the console the same line of text, only now with every letter doubled. Other characters in the line should be left alone, except for exclamation points (!): These should be tripled.

Example: if the input line is:
Hey! My car can't move!!

Then your program should print:
HHeeyy!!! MMyy ccaarr ccaann'tt mmoovvee!!!!!!


Make sure that you comment your code (in places just comment groups of lines here - so you might have a comment that simply says "Reads the input" for the statements that do the prompting and reading).

Note: when is a character a letter? If ch is a char variable, then you can determine if ch holds a letter (upper or lower case, A-Z, a-z) with this method call:
Character.isLetter(ch)

This method returns a boolean value (true means: ch IS a letter; false means it isn't)

Do NOT include import statements in your submission. We input the Scanner class for you.

import java.util.Scanner;

How do i complete this?

Question: Write a program that produces as output the lyrics of the song,"There Was an Old Lady Who Swallowed a Fly," by Simms Taback. Use methods for each verse and the refrain. Here are the song's complete lyrics:

Also, use functional decomposition. No line of code should be repeated.


There was an old woman who swallowed a fly.
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old woman who swallowed a spider,
That wriggled and iggled and jiggled inside her.
She swallowed the spider to catch the fly,
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old woman who swallowed a bird,
How absurd to swallow a bird.
She swallowed the bird to catch the spider,
She swallowed the spider to catch the fly,
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old woman who swallowed a cat,
Imagine that to swallow a cat.
She swallowed the cat to catch the bird,
She swallowed the bird to catch the spider,
She swallowed the spider to catch the fly,
I don't know why she swallowed that fly,
Perhaps she'll die.

There was an old woman who swallowed a dog,
What a hog to swallow a dog.
She swallowed the dog to catch the cat,
She swallowed the cat to catch the bird,
She swallowed the bird to catch the spider,
She swallowed the spider to catch the fly,
I don't know why she swallowed that fly,
Perhaps she'll die.

JGrasp, Java programming help?

I have been trying to figure out this problem for hours, any help is greatly appreciated:

Write a program that reads a positive integer and then finds the smallest power of two that is greater than or equal to the number that are read. For example, if the program reads the value 25, it should note that 32 = 25 is the smallest power of two greater than or equal to 25.

Thanks!

Java Computer Programming Questions HELP APPRECIATED!?

1. What is the return type of a method that does not return a value? (null, void, zero, or int)

2. If max is a static method that is being called from the main method, which calls max, passes in two values, and assigns the returned value to an int?
- int result = max();
- int max(5,3);
- int max(5,3) = result;
- int result = max(5,3);
