Today I badly wished for the keyword "goto" in java to have an implementation - deeply nested if/then/else in loops and I wanted to break out of several levels at once.
What I found was something I have not seen in use anywhere - the possibility to break out of a labeled block!
So, if you, like me have not read chapter 14 of the Java Language Specification - here is a quick tip!
everything:
{
// do something
break everything;
}
breaks out of the block. This is true for loops as well! And with loops it is also possible to address which loop to continue.
outer:
for(int i = 0; i < someLimit; i++)
for(j = 0; j < someLimit;j++)
break outer;
breaks the outer loop
outer:
for(int i = 0; i < someLimit; i++)
for(j = 0; j < someLimit;j++)
continue outer;
continues the outer loop.
