Java Label usage

Example here and explanation under :)

//Here is one benefit of using labels in Java:
block:
{
    // some code

    if(condition) break block;

    // rest of code that won't be executed if condition is true
}

//Another usage with nested-loops:
outterLoop: for(int i = 0; i < 10; i++)
{
    while(condition)
    {
        // some code

        if(someConditon) break outterLoop; // break the for-loop
        if(anotherConditon) break; // break the while-loop

        // another code
    }

    // more code
}


//Another example
outterLoop: for(int i = 0; i < 10; i++)
{
    while(condition)
    {
        // some code

        if(someConditon) continue outterLoop; // go to the next iteration of the for-loop
        if(anotherConditon) continue; // go to the next iteration of the while-loop

        // another code
    }

    // more code
}

A label in java can be set to a block of code and if you specify the label after a break statement, the block will stop executing.
