Java loop structure (b) for the use of the For statement, the following example allows you to fully understand the For loop

Output

Import Java.util.scanner;public class Text10{public static void Main (string[] args) {Scanner sc=new Scanner (system.in); int I,j,n;n=sc.nextint (); for (i=1;i<=n;i++) {for (j=1;j<=n;j++) {System.out.print (i);} System.out.println ();}}}

Output Pyramid * No.

One- , two-, five-minute coins are exchanged for a dollar note, and the total number of coins required for redemption is -how many kinds of redemption methods are there? How many coins are used for each method of redemption?

public class Text16 {public static void main (string[] args) {    int x, y, Z;    for (x=0;x<=50;x++) for (    y=0;y<=50;y++) for (    z=0;z<=50;z++)    if (x+y+z==50) System.out.println ( "One point =" +x+ "two points =" +y+ "Five points =" +z ";}}
