Random number generator in Java
To generate random numbers in Java, use.
import java.util.Random;
Now, take Random class and create an object.
Random num = new Random();
Now, in a loop, use the nextInt() method since it is used to get the next random integer value. You can also set a range, like for 0 to 20, write it as.
nextInt( 20 );
Let us see the complete example wherein the range is 1 to 10.
Example
import java.util.Random;
public class Demo {
public static void main( String args[] ) {
Random num = new Random();
int res;
for ( int i = 1; i <= 5; i++ ) {
res = 1 + num.nextInt( 10 );
System.out.printf( "%d ", res );
}
}
}Output
