Hi Guys I'm having a trouble in stop or repeating a method after another method is failed... what is my code :- void method1() { //code } void method2() { fetchdata() } void method3() { fetchdata2() } void fetchdata() { //code } void fetchdata2() { //code } void button_click() { method1(); method2(); method3(); } so my issue is if fetchdata1() returns null then either process repeat itself or stop don't go to method3() and forward.

void method1() void method2(){ fetchdata(); } void method3(){ fetchdata2(); } void method4(){ fetchdata3(); } void fetchdata() { if(data == null) {go to method1 or stop from executing method2}} void fetchdata2() { if(data2 == null) {go to method2 or stop from executing method3}} void fetchdata3() { if(data3 == null) {go to method3 or stop from executing method4}} void button_click() { method1(); method2(); method3(); method4(); } How to do this :- go to previous method or stop from executing next method
