java program

Write a program that will use a while loop to accept numbers from the keyboard and add them together. As soon as a negative number is entered, exit the loop and display the total. Do not include the negative number in the total.

Assume that minimumPayment is a variable which has a value assigned to it already. Write piece of a program including a do-whileloop that will do the following. Ask the user for a value to store in monthlyPayment. If the amount entered for monthlyPayment is less than minimumPayment, then display an error message and ask for a larger amount. Input the new amount and continue asking for a larger amount until monthlyPayment is greater than or equal to minimumPayment.
