Code
ass Mess1 { public static void main (String[] arg) { int d; d=10; System.out.println(d); Ex1 g; g=new Ex1(); g.a(d); System.out.println(d); } } class Ex1 { int p; Ex1() { p=0; } public void a (int p) { this.b(p); this.printVals(p); this.b(this.p); } private void b (int q) { this.printVals(q); } private void printVals(int r) { System.out.println(r); } }
Output
