抛出异常但不停止程序的最佳方法是什么？

Question

Please find below an example of my need. Indeed, I don't want to close the entire process because even if it throw an Exception, it can continue.

Loop

// set a lot of variables and execute some methods
for (int i = 0, i < items.length; i++) {
     // blablabla
     myMethod()
     // blablabla2
}
// some code here also

MyMethod()

// blabla
if (!found)
     throw new EndCurrentProcessException()
// blabla

EndCurrentProcessException

public void EndCurrentProcessException() {
     ??? What I'm supposed to put here to stop the loop iteration ???
}

Maybe that used throw new is not the good way to do.

I hope it is clear, if it is not, do not hesitate to ask me more informations.

Answer 1

Don't throw an exception. Handle the method failure whichever way you see fit.

In your example, modify the myMethod() method to return boolean true if it was successful and false if it was not:

Loop:

// set a lot of variables and execute some methods
for (int i = 0, i < items.length; i++) {
   // blablabla
   if (!myMethod()) {
       // Skip this particular ITEM...
       continue;
       // Or whatever you want.
   }
   // blablabla2
}

MyMethod():

public boolean myMethod() {
    // ... Method code ...
    if (!found) {
        return false;
    }
    // ... Possibly more Method code ...
    return true;
}

Try to use try-catch statement.

for (int i = 0, i < items.length; i++) {
    // blablabla
    try {
        myMethod();
    } catch(EndCurrentProcessException e){
        // do something or continue;
        continue;
    }
    // blablabla2
 }
 // some code here also
