You are to write a program that generates the second, third, and fourth powers of a list of
whole numbers from 1 to n where n is input by the user. Write a Java program to do this.
First, ask the user for the largest of the whole numbers to use (n). Second, output column
headers (see below, n, n^2, n^3, n^4). Then, use a for loop to iterate from 1 to n, computing
each of that loop variable to the second power, third power and fourth power. Assuming
your loop variable is called i, you can do this either as i*i or Math.pow(i,2). To output the
values in nice columns as shown below, separate each output with a tab (“\t”). This is
similar to using \n for a new line.
Test your program with different input values such as 5, 10, 1, 0 and -1. For 0 and -1, you
should get no output at all. If you wrote your loop correctly, that will be the case.
Debugging tip: If you get incorrect results when running code that contains a loop, place
some print statements inside the loop to print the values of any variables that you think
might be involved in the errors. This helps you check what your loop is actually doing.
Write one additional program which itself contains two loops. You will have to decide
which loop type to use and how to write each one. Both loops will have a loop body that
consists of a computation and an output.
instance, it will output 1, 3 (1+2), 6 (1+2+3), 10 (1+2+3+4), etc (on separate lines).
than 100, again outputting results as you go.
You will have to decide what type of loops to use and how to write each, and what other
variables and instructions are needed in your program.
