Java random number between 1 and 10 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: math.random java between 1 and 10

((int) (Math.random()*(maximum - minimum))) + minimum;

Example 4: java random number between 100 and 999

int upperBound = 999;
int lowerBound = 100;
int number = lowerBound + (int)(Math.random() * ((upperBound - lowerBound) + 1));
