if you haven't read that before then check out : Introduction to loop and its types .
For example if you want to print out table of any number , given by the user then you can use "For" loop for that process and the code will become:
package table;import java.util.Scanner;public class Table{public static void main(String[] args){Scanner input=new Scanner(System.in);System.out.print("Enter an integer: ");int a=input.nextInt();for(int i=1;i<=10;i++){int b=a*i;System.out.println(a+" * "+i+"= "+b);}}}
