Outcomes of a Dice || Generating Random numbers in Java

import java.util.*; class GenerateRandomNumber { public static void main(String args[]) { int i=0; Random r=new Random(); Scanner sc=new Scanner(System.in); System.out.println("How many random numbers ,do you want to generate?"); int value=sc.nextInt(); System.out.println(); System.out.println("Generating Numbers"); for(i=0;i<value;i++) { int n=r.nextInt(6) + 1; System.out.println(n); } } } /*In the loop it is written: int n=r.nextInt(6) + 1; Here 6 inside the parentesis is the maximum value of random number,since here we are considering a dice so I have set that to 6. And the +1 indicates the minimum possible number generated.You have to include import java.util.*; library to use Random(). */

Java program on two dimension Matrix of String or Characters.

import java.util.*; class CharArray { public static void main(String args[]) { String a[][]; a=new String[3][3]; int i=0,j=0; Scanner sc=new Scanner(System.in); System.out.println("Enter your characters"); for(i=0;i<3;i++) { for(j=0;j<3;j++) { a[i][j]=sc.next(); } } System.out.println(); for(i=0;i<3;i++) { for(j=0;j<3;j++) { System.out.print(a[i][j]+" "); } System.out.println(); } } } /* Here I have used 3*3 matrix, you can also form any multi-dimension matrix by providing its size using scanner.*/
