Key words in While loop:
In a while loop, the key Java keywords and concepts used are:
while – This keyword is used to start a while loop. It repeatedly executes a block of code as long as the given condition is true.Loop Condition – The condition inside the parentheses (no1 < 10) determines if the loop should continue or stop.Loop Body – The block of code inside {} runs repeatedly while the condition is true.Loop Control Variable – A variable (no1 in your case) that changes inside the loop to eventually break the loop.Increment/Decrement Statement – no1++ increases the loop variable to prevent an infinite loop.Break Condition (Implicit) – The loop stops when the condition (no1 < 10) becomes false.System.out.println – Used inside the loop to print output during each iteration.
Task 1:
package loopingDemo;public class First_Looping { public static void main(String[] args) {// TODO Auto-generated method stub int total=0; int no1=0; int no2=3; while(no1<10) { no1=no1+1; total=no1*no2; System.out.println(no1+"*"+no2+"="+total); } }
Output
1*3=32*3=63*3=94*3=125*3=156*3=187*3=218*3=249*3=2710*3=30
Task 2:
package loopingDemo;public class First_Looping { public static void main(String[] args) {int count=1; while(count<=5) { System.out.println("12345"); count++; } }}
Output
1234512345123451234512345
