Answer 1

A label can precede only a statement, not a declaration.

Since in this statement you both declare and initialize a variable, it is considered a declaration, not a statement, so the label becomes illegal.

If you want to put a label on the part of the line that is currently the initialization, you should use:

AlertDialog.Builder localBuilder15;
label422: localBuilder15 = new AlertDialog.Builder(testActivity.this);

This way, your label marks a statement, not a declaration.

But of course, as you have already been told, the label is simply superfluous here. If you don't have any break statements within your statement, it's simply not useful.

Note:

• There is no goto in Java, so labels can't be used as jump targets.
• If you want to break to a label, the label has to mark a statement that encloses the block containing the break statement. The statement marked by the label is always just the one that follows it up to the next ; , or if the label marks a compound statement, its ending } . So the label you created only marks the new statement, and no break statement in the statements after that will be in its scope.
