Change in one vairable is not reflected in the other variable

Question

Question/ Objective / Doubt:
during the execution of the program ,change in the member/variable of the class is not reflected in the other variable which is the dependent variable of the previous one;
Program / code:
class Simple {
     static int [][] valOne;
     static int [][] valTwo; //values depends on ?a? values
     // static int [][] valTwo=Library.different(valOne);  this doesn't work
     // static { valTwo=Library.different(ValOne); } // this doesn't fulfill what i expect
     Simple(int a[][]){
       valOne=a;
       ValTwo=Library.different(a); //say some static method
     void change(int r,int c,int n){
       //one of the ValOne is changed
       valOne[r][c]=n;
class Library{
     static int [][]different(int num[][]){
          //some computations
          return intArr;//returns a values with respect to the incoming variable
Description / Explanation:
during execution:
when change method is invoked to change valOne ; I want this change to be reflected in valTwo But this does not happen.....as valTwo in initialised only in the constructor
My Try / My Effort:
// static int [][] valTwo=Library.different(valOne); //this doesn't fulfill
// static { valTwo=Library.different(valOne); } // this doesn't fulfill
i declared variable as static so that this would solve the problem..
sorry if there any wrong in naming convention...

Answer 1

it seems u are scolding me . my above comment is after seen this program
// Demonstrate static variables, methods, and blocks.
class UseStatic {
  static int a = 3;
  static int b;
  static void meth(int x) {
    System.out.println("x = " + x);
    System.out.println("a = " + a);
    System.out.println("b = " + b);
  static {
    System.out.println("Static block initialized.");
    b = a * 4;
  public static void main(String args[]) {
    meth(42);
output:
Static block initialized
x=42
a=3
b=12
i like to know more. that's why i am continuing even after the objective is solved
