Using for loop you can repeatedly loops until a particular condition is satisfied. The general form of the for statement can be expressed as follows: for (initialization; condition for terminating loop;increment) { … do while Loop Example in Java Programs 1) Print your name 10 times. Statement 1 sets a variable before the loop starts (int i = 0). Statement 2 defines the condition for the loop to run (i must be less than 5). Programs are called classes. If the condition is true, the loop will start over again, if it is false, the loop will end. Watch Now. These programs can be asked from control statements, array, string, oops etc. Program Logic: previousNumber is initialized to 0 and nextNumber is initialized to 1; For Loop iterates through maxNumber; Display the previousNumber; Calculates sum of previousNumber and nextNumber; Updates new values of previousNumber and nextNumber; Java code using While Loop.
