Missing return statement

[Aenohe]

Cant find mistake in this code - can some1 help - please.
Keep getting "missing return statement" when i try to compile.

    public boolean search(String searchString){
        int index = 0;
        boolean found = false;
        while(index < notes.size() && !found) {
            String note = notes.get(index);
            if(note.contains(searchString)) {
                found = true;
            }
            else {
                index++;
            }
            }
        if(found) {
            System.out.println("Found search term in note: " + notes.get(index));
        }
        else {
            System.out.println("Search term not found.");
        }
    }

In the first line of the code, the method declaration, you specified that the return type of the method is "boolean." However, you never return a boolean value (true or false). It looks like you would want to return "true" if the search finds something and "false" if it does not. The code would look like this:

public boolean search(String searchString) {
	    int index = 0;
	    boolean found = false;
	    while(index < notes.size() && !found) {
	        String note = notes.get(index);
	        if(note.contains(searchString)) {
	            found = true;
	        }
	        else {
	            index++;
	        }
	    }
	    if(found) {
	        System.out.println("Found search term in note: " + notes.get(index));
	        return true;
	    }
	    else {
	        System.out.println("Search term not found.");
	        return false;
	    }
}

If you don't want the method to return a boolean value at all, just change boolean in the method declaration to "void" and don't add the return statements that I put in.

Thanks a bunch.

Feel a bit embarrassed i thought that it is enough to have

 found = true;

as statement.

I vaguely remember seeing some language where you write a statement that looks like you're assigning a value to the name of the method, and that sets the return value. But Java doesn't work that way.

VBA does that - not sure if VB has the same syntax, but it certainly confused the hell out of me.

That code is actually from the book but they have obviously made mistake which @zirbinator kindly explained to me.

System.out.print("Enter another number: ");
b = van.nextDouble();
c = a+b;
exponent=1;
while (exponent <= 200) {
System.out.println(+exponent+ " ");
exponent++;

}
while (c <= exponent ) {
System.out.println("\nThe power is " +c+ " ");
c++;
}

}
}

i cant understand why its missing return statement

public String PowerFunc(){

That says the method PowerFunc (which should be powerFunc according to naming standards) returns a String.
As it stands that method does not return a String...or anything for that matter.

vanhongin143, even the question is quite similar to the original not related. Next time, please start a new thread in relevant sub-forum.
