How to write Junit test case for code below that sorts 3 numbers?

I need to write 5 different unit test for the scenario below. How can I achieve that? I am poor on testing so your help will be really appreciated. Thanks in advance.

This is class for doing the sorting of three number.

public class SortNumber {

public double[] Sort3(double value1, double value2, double value3) {

    double sorted[] = new double[3];

    if(value1>=value2 && value1>=value3) {
        sorted[2] = value1;
        if(value2<=value3) {
            sorted[0] = value2;
            sorted[1] = value3;
        }
        else {
            sorted[0] = value3;
            sorted[1] = value2;
        }
        
    }
    else if (value2>=value1 && value2>=value3) {
        sorted[2] = value2;
        if(value1<=value3) {
            sorted[0] = value1;
            sorted[1] = value3;
        }
        else {
            sorted[0] = value3;
            sorted[1] = value1;
        }
    }
    else {
        sorted[2] = value3;
        if (value2<=value1) {
            sorted[0] = value2;
            sorted[1] = value1;
        }
        else {
            sorted[0] = value1;
            sorted[1] = value2;
        }
    }
    
    return sorted;
}

}

Class below contains main method:

public class Calculate {

public static void main(String[] args) {
    
    SortNumber sn = new SortNumber();
    sn.Sort3(44, 5, 100);
    
}

}
