Java Program to perform Matrix addition

{

}
void display1()
{
for(int i=0;i<3;i++)
  {
   for(int j=0;j<3;j++)
        System.out.print(a[i][j]+" ");
     System.out.println("\t");
  }
}
void display2()
{
for(int i=0;i<3;i++)
  {
   for(int j=0;j<3;j++)
        System.out.print(b[i][j]+" ");
     System.out.println("\t");
  }
}

{
for(int i=0;i<3;i++)
  {
   for(int j=0;j<3;j++)
       sum[i][j]=a[i][j]+b[i][j];
  }

  }
}
public static void main(String s[])
