How to use the return to retrieve a value out of an if statement? I don't want to return immediately, just like that:
if(){
return "something";
}
This isn't working for me, because if the return is successful the method returns, but I need to return it and when the return is complete to continue the actions in the method.
Try something like:
String result = null;
if(/*your test*/) {
result = "something";
}
return result;
This should be the easiest way in your case
return yourCondition ? "ifTrue" : "ifFalse";
If you want to "return" values from a method without actually returning from the message, then you have to define setter methods on the calling class and call them, like this:
public class Caller {
private boolean someState;
// ...
public void doSomething() {
// the method call
Worker w = new Worker(this);
int result = w.workForMe();
}
public void setState(boolean state) {
this.someState = state;
}
}
And the Worker
public class Worker {
private Caller caller;
public Worker(Caller caller) {
this.caller = caller;
}
public int workForMe() {
// now the conditions:
if(clearBlueSky) {
// this emulates a "return"
caller.setState(true);
}
// this returns from the method
return 1;
}
}
return (there's no way back).Store your string in a variable.
String s = null;
if( somecondition ) {
s = "something";
}
// do other stuff
return s;
return is for methods. You probably want something like this:
int foo;
if (someCondition) {
foo = 1;
} else {
foo = 2;
}
Use a finally block or save the return value in a variable that you return at the end of your code.
Do you mean something like
String result = "unknown";
if(condition){
result = "something";
}
// do something.
return result;
