Java - get random float number

1. Generate random float with ThreadLocalRandom class

public static float nextFloat() {
    return ThreadLocalRandom.current().nextFloat();
}

Example:

System.out.println(nextFloat()); // 0.5261965
System.out.println(nextFloat()); // 0.23931652
System.out.println(nextFloat()); // 0.8099988

2. Generate random float with Random class

public static float nextFloat2() {
    return new Random().nextFloat();
}

Example:

System.out.println(nextFloat2()); // 0.0030902028
System.out.println(nextFloat2()); // 0.77623594
System.out.println(nextFloat2()); // 0.39141566
