Initialize class properties What principles do you have and how do you do it?

Generator(){
    var1 = getVar1();
    var2 = getVar2();        
}

Generator(){
    initVar1();
    initVar2();        
 }

iniVar1(){
    var1 = ...
}
iniVar2(){
    var2 = ...
}

You need to know var1 to get var2 What principles do you have, including these little things...

If you have many fields to initialize, consider the builder pattern.

For simple cases

class Temp{
int x;
iny y;

public Temp(int x, int y){
    this.x = x;
    this.y = y;
}
public Temp(int x){
    Temp(x, null); // y is null or the default value
}

It's designed in the same way.
