[Solved] java how to convert for loop to do while loop

by 


int sum = 0;
    int num;
    int i = 0;
    System.out.print("Enter number: ");
    num = sc.nextInt();
    do{
    sum += i;
    i++;
    }
    while ( i <=num );

    System.out.println("The sum is " + sum);

Initialize i to zero, since do-while does first before checking, as opposed to for that checks first before doing. And your do-while will work the same as your for.Or else your do-while will have a sum of 1 even if your num is 0. As opposed to your for that will have sum=0 if num is 0.
