Generate a random string in Java
Let us first declare a string array and initialize −
String[] strArr = { "P", "Q", "R", "S","T", "U", "V", "W" };Now, create a Random object −
Random rand = new Random();
Generate random string −
int res = rand.nextInt(strArr.length);
Example
import java.util.Random;
public class Demo {
public static void main(String[] args) {
String[] strArr = { "P", "Q", "R", "S","T", "U", "V", "W" };
Random rand = new Random();
int res = rand.nextInt(strArr.length);
System.out.println("Displaying a random string = " + strArr[res]);
}
}Output
Displaying a random string = R
Let us run it again to get distinct random string −
Displaying a random string = Q
