Methods : Make my method with many input variables with out overloading

is there Any Way To Make my Method Take many input variable but with out overloading ... could be my question not clear ... I mean Like That :

if I Have This Method 

public void setValues (int val1,int val2 ,String val3){
}

what I want is : use this method with many way 

setValues (val1,val2)

OR 

setValues (val3)

why I want to do that with out overloading : Because if i have as example 10 variable i want to add many method with overloading but i don't like that ...

is there any way helps me to check variable or skip it in the same method ..

Thanks for help .

You can use varargs future to partially solve your problem http://docs.oracle.com/javase/1.5.0/docs/guide/language/varargs.html This can be done if you have parameters of a same type.

But it will require that you will pass variables with the same type as a last param. It is not completely what you want, but it is a small workaround.

No there's no way to do that in Java without method overloading. One alternative would be to group those parameters which are related and make them fields of a class. Then the method would take an instance of that class as a parameter, and which ever parameters were optional would then be null.
