random number between bounds java code example

Example 1: java random number

import java.util.Random;

Random rand = new Random();

// Obtain a number between [0 - 49].
int n = rand.nextInt(50);

// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;

Example 2: java random numbers in specific range

import java.util.Random;

Random rand = new Random();
int random_integer = rand.nextInt(upperbound-lowerbound) + lowerbound;

Example 3: random number in range java

(int)(Math.random() * ((max - min) + 1)) + min
Copy

Example 4: java random number generator in range

int rand = ThreadLocalRandom.current().nextInt(x,y);
