Generating a random value between a set range in java [duplicate]

• How do I generate random integers within a specific range in Java? 49 answers

I am currently working on a java project that requires me to generate a random percentage within a range values a high (stored in a variable called max) and a low (stored in a variable of min) I am fairly new to java and cannot figure out the errrors i am getting, when I am able to get the code to compile it generates a 0.0. Any help would be appreciated.

public static void runSimulation() {
    Random randInvest = new Random();
    randInvest = minSalRange + (float)(Math.random() * maxSalRange);
    System.out.println("The random generated number was"+randInvest);
}

Here is the version I am able to run which kicks out 0.0 every time

public static void runSimulation() {
    randInvest = minSalRange + (float)(Math.random() * maxSalRange);
    System.out.println("The random generated number was"+randInvest);
}
