Seriously this time, consider the following Unix timestamp:

The "Z" means the Z timezone which is basically a short for UTC.

Now, airplane pilots and military often spell as follow:
tap: tango alfa papa
zoo: zulu oscar oscar

So, the Z timezone slowly became the "Zulu" timezone.

Denoting UTC as Z began around 1950 and it simply means "zero offset" to UTC.

Damn, I posted basically the same thing above. See here:


I am surprised that java developers don't seem to know how to create output parameters. As stated in my first post above, I am not saying this is a good idea but here is how you do it if you need to:

int[] out1 = new int[1];
int[] out2 = new int[1];
int[] out3 = new int[1];

void setOutParameters(int[] v1,int[] v2, int[] v3) {
    v1[0] = 1;
    v2[0] = 2;
    v3[0] = 3;


System.out.println(out1[0] + "" + out2[0] + " " + out3[0]); // prints "1 2 3"

This is silly, for:

1. pass by reference (yah, probably not happening, but if I can choose only one, I'd take it.)
2. output variables. Sometimes you don't want to make yet another class/struct/etc.

an array will make a fine wrapper object and make the intention clear if you ever need to do this which is rare.

int firstNumber = 24;
int secondNumber = 26;
int[] result = new int[1];

add (firstNumber,secondNumber,result);

System.out.println(result[0]); // prints 50

void add(int firstNumber,int secondNumber,int[] result) {
    result[0] = firstNumber + secondNumber;

I do have a String library that use use the passed StringBuilder as an input/output parameters to avoid creating new builders and strings on every string operation although.
