Java ThreadLocalRandom doubles() method

The doubles() method of Java ThreadLocalRandom class returns an effectively unlimited stream of pseudorandom double values. Each value must lie between 0 and 1. This method overrides doubles in class Random.

Syntax:

Parameter:

NA

Returns:

This method returns a stream of pseudorandom double values.

Example

Test it Now

Output:

stream of pseudorandom double value is: [email protected]

Java ThreadLocalRandom doubles(long streamSize) method

The doubles(long streamSize) method of Java ThreadLocalRandom class returns a stream producing the given streamSize number of pseudorandom double values. Each value must conform to the given 0 (inclusive) and 1 (exclusive). This method overrides doubles in class Random.

Syntax:

Parameter:

streamSize - It is the number of values to generate

Returns:

This method returns a stream of double values.

Exception:

IllegalArgumentException: This exception will throw if the streamSize is less than zero.

Example 1

Test it Now

Output:

stream of double value is: [email protected]

Example 2

Test it Now

Output:

Exception in thread "main" java.lang.IllegalArgumentException: size must be non-negative

	at tests.JavaNextIntExample1.main(ThreadLocalRandomDoublesExample2.java:8)

Java ThreadLocalRandom doubles(double randomNumberOrigin, double randomNumberBound) method

The doubles(double randomNumberOrigin, double randomNumberBound) method of Java ThreadLocalRandom class returns an effectively unlimited stream of pseudorandom double values. Each value must conform to the given origin (inclusive) and bound (exclusive). This method overrides doubles in class Random.

Syntax:

Parameter:

randomNumberOrigin: It is the origin (inclusive) of each random value.

randomNumberBound: It is the bound (exclusive) of each random value.

Returns:

This method returns a stream of pseudorandom double values.

Exception:

IllegalArgumentException: This exception will throw if randomNumberOrigin is greater than or equal to randomNumberBound.

Example 1

Test it Now

Output:

stream of pseudorandom double value is: [email protected]

Example 2

Test it Now

Output:

Exception in thread "main" java.lang.IllegalArgumentException: bound must be greater than origin
	at java.base/java.util.concurrent.ThreadLocalRandom.doubles(Unknown Source)
	at tests.JavaNextIntExample.main(ThreadLocalRandomDoublesExample2.java:7)

Java ThreadLocalRandom doubles(long streamSize, double randomNumberOrigin, double randomNumberBound) method

The doubles(long streamSize, double randomNumberOrigin, double randomNumberBound) method of Java ThreadLocalRandom class returns a stream producing the given streamSize number of pseudorandom double values. Each value must conform to the given origin (inclusive) and bound (exclusive). This method overrides doubles in class Random.

Syntax:

Parameter:

streamSize - It is the number of values to generate

randomNumberOrigin - It is the origin (inclusive) of each random value

randomNumberBound - It is the bound (exclusive) of each random value

Returns:

This method returns a stream of pseudorandom double values.

Exception:

  1. IllegalArgumentException: This exception will throw if the streamSize is less than zero.
  2. IllegalArgumentException: This exception will throw if the randomNumberOrigin is greater than or equal to randomNumberBound.
