while using BufferedReader to read 2 numbers in same line I was having an Error: java.lang.NumberFormatException: For input string: "2 3"

Iam new to BufferedReader. I was trying to take input of 2 numbers in the same line for ex: 2 3. For that I have written the below code.

import java.io.*;
public class Main
{
	public static void main(String[] args)throws IOException{
		BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
		int N = Integer.parseInt(bufferedReader.readLine().trim());

        int M = Integer.parseInt(bufferedReader.readLine().trim());
        System.out.println("N="+N+"M="+M);
	}
}

So Iam encountering the below error.

Exception in thread "main" java.lang.NumberFormatException: For input string: "2 3"

What's wrong with the code. Thanks in advance.

When taking in multiple inputs on the same line, you should define a character that will be used to separate inputs. In your example, it seems like this is done through whitespace.

You need to create an array of responses from the single line input as a string using split(), and then assign them to the variables you need using Integer.parseInt().

import java.io.*;
public class Main
{
    public static void main(String[] args) throws IOException {
        // Create BufferedReader and two ints
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
        int N, M;

        // Take in inputs from user, and split them into an array using whitespace
        // '\\s+' matches at any whitespace size
        String[] inputs = bufferedReader.readLine().split("\\s+");

        N = Integer.parseInt(inputs[0]);
        M = Integer.parseInt(inputs[1]);

        System.out.println("N=" + N + " M=" + M);
    }
}
