Conversion from int to long:

In this tutorial we will learn how to convert an int type value to long type data.

Description:

This program will take an int value from console and provide a conversion to long data. The line int myint = Integer.parseInt(buffreader.readLine()); is used to read the int value from console and store in myint variable. The line long mylong = (long)(myint); converts the myint int type value to mylong long type data.

Code:

import java.io.*;

class inttolong {
	public static void main(String[] args) {
		try {
			BufferedReader buffreader = new BufferedReader(
					new InputStreamReader(System.in));
			System.out.println("Enter the int value:");
			int myint = Integer.parseInt(buffreader.readLine());
			long mylong = (long) (myint);
			System.out.println("Convert value from int to long is: " + mylong);
		} catch (Exception e) {
			System.out.println(" Error " + e);
		}
	}
};
