[RESOLVED] What is a " label "?

[eranga262154]

Hi ….

Can you explain what is a label, which is used with loops, with the following example?

I found it from a book. But still can't understand this code.


boolean found = false;

outer: for(int row=0; row<10; row++)

{

inner: for(int col=0; col<10; col++)

{ // some code which may change found to true

if(found)
{
break outer; // jumps to outer loop

}}}

A label allows you to break out of a certain loop. If you have three loops nested and you want to break out of the outermost loop, then how is the compiler suppose to know what loop to break out of?

A normal break statement simply looks like this:

break;

That's very correct.
But in addition: The label is the physical address of command, you can consider it "a Name" for the following line.
