I am not sure, if I understood your question right. 
In my opinion your code is okay but it will not return the new value
11 in i.
Instead you should write

public func1(){

int i = 10;
i = func2( i );    //set value of function to i
System.out.println( i )  ===> 11

}
public int func2(int arg){   // 'int' is important for return value
    arg = arg + 1;
    return arg;	//pushes the value back
}
