java Random ints() Method

---

---

Description

The java Random ints() method returns an effectively unlimited stream of pseudorandom int values. A pseudorandom int value is generated as if it's the result of calling the method nextInt().

Declaration

Following is the declaration for java.util.Random.ints() method.

public IntStream ints()

Parameters

NA

Return Value

The method call returns a stream of pseudorandom int values.

Exception

NA

java Random ints​(int randomNumberOrigin, int randomNumberBound) Method

Description

The java Random ints​(int randomNumberOrigin, int randomNumberBound) method returns an effectively unlimited stream of pseudorandom int values, each conforming to the given origin (inclusive) and bound (exclusive).

Declaration

Following is the declaration for java.util.Random.ints​(int randomNumberOrigin, int randomNumberBound) method.

public IntStream ints​(int randomNumberOrigin, int randomNumberBound)

Parameters

randomNumberOrigin − the origin (inclusive) of each random value

randomNumberBound − the bound (exclusive) of each random value

Return Value

The method call a stream of pseudorandom int values, each with the given origin (inclusive) and bound (exclusive).

Exception

IllegalArgumentException − if randomNumberOrigin is greater than or equal to randomNumberBound

java Random ints​(long streamSize) Method

Description

The java Random ints​(long streamSize) method returns a stream producing the given streamSize number of pseudorandom int values. A pseudorandom int value is generated as if it's the result of calling the method nextInt().

Declaration

Following is the declaration for java.util.Random.ints​(long streamSize) method.

public IntStream ints​(long streamSize)

Parameters

long streamSize − the number of values to generate.

Return Value

The method call a stream of int values.

Exception

IllegalArgumentException − if streamSize is less than zero.

java Random ints​(long streamSize, int randomNumberOrigin, int randomNumberBound) Method

Description

The java Random ints​(long streamSize, int randomNumberOrigin, int randomNumberBound) method returns a stream producing the given streamSize number of pseudorandom int values, each conforming to the given origin (inclusive) and bound (exclusive).

Declaration

Following is the declaration for java.util.Random.ints​(long streamSize, int randomNumberOrigin, int randomNumberBound) method.

public IntStream ints​(long streamSize, int randomNumberOrigin, int randomNumberBound)

Parameters

long streamSize − the number of values to generate.

Return Value

The method call a stream of int values.

Exception

IllegalArgumentException − if streamSize is less than zero.

Getting a Stream of Random Integer Numbers Example

The following example shows the usage of Java Random ints() method. Firstly, we've created a Random object and then using ints() we retrieved a stream of random int values and printed first value.

package com.tutorialspoint;

import java.util.Random;
import java.util.stream.IntStream;

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

      // create random object
      IntStream randomNoStream = new Random().ints();
      // print a random int value
      randomNoStream.limit(1).forEach( i -> System.out.println(i));
   }    
}

Output

Let us compile and run the above program, this will produce the following result.

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

      // create random object
      IntStream randomNoStream = new Random().ints(5,6);
      // print a random int value
      randomNoStream.limit(1).forEach( i -> System.out.println(i));
   }    
}

Output
