如何限制功能，使其不会引发任何异常

Question

如何限制一个函数，使其不能抛出任何异常？

Answer 1

Catch all exception in the method.

public void myMethod() {
    try {
       // do something
    } catch (Exception e) {
       e.printStackTrace();
    }
}

if you want to catch any kind of Exception or Error including OutOfMemoryError or ThreadDeath etc use

    } catch (Throwable t) {

Answer 2

Just wrap all of your code in a try catch block.

public void someMethod(){
 try{
  //your code
 }catch (Exception e){
   //do nothing
 }
}
