Java User Input and Difference between readInt and nextInt?

Question

What is wrong with this?

import java.io.*;

class TUI{

    public static void main(String[] args) {

        System.out.println(\"Enter the two numbers:\");
            


        

Answer 1

readInt is used with datainputstream class. nextInt with scanner class and you need to create a scanner object inorder to get input values. i.e

java.util.Scanner obj=new java.util.Scanner(System.in);
      int x=obj.nextInt();

Objective of both is the same to read integer values.
