Random Class next() method

• next() method is available in java.util package.
• next() method is used to return the pseudo-random number in bits.
• next() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• next() method does not throw an exception at the time of returning random bits.

Syntax:

    protected int next(int ran_bit);

Parameter(s):

• int ran_bit – represents the random bits (ran_bit).

Return value:

The return type of the method is int, it returns the pseudo-random number from this Random generator.

Example:

// Java program to demonstrate the example 
// of int next(int ran_bit) method of 
// Random

import java.util.*;

public class NextOfRandom {
 public static void main(String args[]) {

  // Instantiates Random object
  Random ran = new Random();

  // By using next() method is
  // to return the next to next
  // pseudo-random number
  int val = ran.nextInt();

  // Display val
  System.out.println("ran.nextInt(): " + val);
 }
}

Output

RUN 1:
ran.nextInt(): -1105563452

RUN 2:
ran.nextInt(): -1839120956

RUN 3:
ran.nextInt(): -154633366
