Given an int variable n that has already been declared, write some code that repeatedly reads a value into n until at last a number between 1 and 10 (inclusive) has been entered.
ASSUME the availability of a variable, stdin, that references a Scanner object associated with standard input.
do
{
n = stdin.nextInt();
}
while (n > 10 || n < 1);

- Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have already been declared, use a while loop to compute the sum of the cubes of the first n whole numbers, and store this value in total. Use no variables other than n, k, and total and do not modify the value of n.
- Given int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. Thus your code should put 11 + 22 + 33 +... + 4949 + 50*50 into total. Use no variables other than k and total.
- Write a statement that increases the value of the int variable total by the value of the int variable amount. That is, add the value of amount to total and assign the result to total.
- Given an int variable n that has already been declared and initialized to a positive value, use a while loop to print a single line consisting of n asterisks. Use no variables other than n.
- Given an int variable k that has already been declared, use a while loop to print a single line consisting of 88 asterisks. Use no variables other than k.
- Write the definition of a method min that has two int parameters and returns the smaller.
