what is while?

In Java, the while loop is used to execute a block of code repeatedly as long as a given condition is true.

public class While {

public static void main(String[] args) {

task 1

the i value is 0,
the condition is (i<5),
print statement(your choise),
loop by i=i+1

                int i=0;
        while(i<5) { 
            System.out.println("1");  //ANS = 1 1 1 1
                i=i+1;
            }

task 2

the i value is 5,
the condition is (i>=1),
print statement(your choise),
loop by i=i-1


    int i=5;
    while(i>=1) {
        System.out.println(i);   // ANS = 5 4 3 2 1
        i=i-1;

task 3

the i value is 1,
the condition is (i<=10),
print statement(your choise),
loop by i=i+2

                int i=1;
        while(i<=10) {
            System.out.println(i);   // ANS = 1 3 5 7 9
            i=i+2;
        }

task 4

the i value is 0,
the condition is (i<10),
print statement(your choise),
loop by i=i+2.

                int i=0;
        while(i<10) {
            System.out.println(i);   // ANS = 0 2 4 6 8
            i=i+2;

    }

}

}
