Hi all
I happen to learn that java is able to use break keyword.
However, I read from some book saying that some java programmer doesn't recognize break key word...some do...depending on the person writing the codes.
So, do java really accept break keyword?

Sure you've got both ordinary and named breaks in Java. There's a faint touch of goto in break, and goto is something that should be avoided according to structured programming. Therefore some programmers may avoid break (and continue and some return cases) but that's a personal decision. You don't have to make extensive use of everything just because it's allowed.

If you allow gotos without restrictions programmers can jump back and forth all over the place creating an intertwined web of statements virtually impossible to understand and maintain. This is unstructured programming and it leads to complex programs.
The purpose of structured programming is to lower the structural complexity of programs. This is accomplished by not making use of gotos but instead use only a limited few selected control structures ones with specific properties. Those are the ones you see in most modern languages today; if-then-else, while-do, switch-case etcetera.
It was shown that those were sufficient and that goto wasn't needed and that programs became less complex. So hardcore structure programming affectionados prohibit goto totally, but others considers a limited use of statements with a certain "goto-ness" to them, such as break, continue and return, useful.
So according to structured programming gotos should be avoided because they increase the structural complexity of programs. Java offers alternatives to many common uses of goto. There's a short section in The Java programming Language by Gosling. 7.10 What, No goto?
