The setSeed() method of Random class sets the seed of the random number generator using a single long seed.
Syntax:
public void setSeed()
Parameters: The function accepts a single parameter seed which is the initial seed.
Return Value: This method has no return value.
Exception: The function does not throws any exception.
Program below demonstrates the above mentioned function:
Program 1:
// program to demonstrate the // function java.util.Random.setSeed() import java.util.*;
public class GFG {
public static void main(String[] args)
{
// create random object
Random r = new Random();
// return the next pseudorandom integer value
System.out.println( "Random Integer value : "
+ r.nextInt());
// setting seed
long s = 24 ;
r.setSeed(s);
// value after setting seed
System.out.println( "Random Integer value : " + r.nextInt());
}
} |
Output:
Random Integer value : -2053473769 Random Integer value : -1152406585
Program 2:
// program to demonstrate the // function java.util.Random.setSeed() import java.util.*;
public class GFG {
public static void main(String[] args)
{
// create random object
Random r = new Random();
// return the next pseudorandom integer value
System.out.println( "Random Integer value : "
+ r.nextInt());
// setting seed
long s = 29 ;
r.setSeed(s);
// value after setting seed
System.out.println( "Random Integer value : "
+ r.nextInt());
}
} |
Output:
Random Integer value : -388369680 Random Integer value : -1154330330
