Please Help with my Java, returning refrence value! Help!!!

Question

public class HelloWorld{
public static float max(float[] nums) {
if (nums[0] > nums [1] && nums[0] > nums[2]) {
return nums[0];
}
if (nums[1] > nums [0] && nums[1] > nums[2]) {
return nums[1];
}
if (nums[2] > nums[0] && nums[2] > nums[1]) {
return nums[2];
}
return 0;
}
public static float min(float[] nums) {
if (nums[0] < nums [1] && nums[0] < nums[2]) {
return nums[0];
}
if (nums[1] < nums [0] && nums[1] < nums[2]) {
return nums[1];
}
if (nums[2] < nums[0] && nums[2] < nums[1]) {
return nums[2];
}
return 0;
}
public static float[] rgb2hsv(float r,float g, float b) {

It's returning a refrence value and I don't know why. It's
