Step Loop: Here the increment or decrement operator changes by more than one.
For Example:
Print all the multiples of 5 up to 100.
for (i=5; i<=100; i=i+5)
{
System.out.println(i);
}
Examples of programs based on loops:
Program 5 Write a program to input a number and print the number is composite number or not.
1 import java.util.*;
2 class composite_number
3 {
4 public static void main ()
5 {
6 Scanner sc= new Scanner (System.in);
7 int n,i,count=0;
8 System.out.print("Enter a number: ");
9 n=sc.nextInt();
10 for (i=1; i<=n;i++)
11 {
12 if(n%i==0)
13 {
14 count++;
15 }
16 }
17 if(count>2)
18 System.out.println(n+" is Composite Number");
19 else
20 System.out.println(n+" is not Composite Number");
21 }
22 }
