java

yesterday, one of my friends asked me

to build a heap sort algorithm in java language.

but yesterday, there was a live concert

in which i my band perform,

so i started coding today midi.

it seemed kind of easy task,

but soon after i started that,

i could not correct some bug, little but critical.

some minutes later,

i noticed that was caused with the way to use some method

(i was still writing a Java code like C++ code)

i realized that it is important to be used to this kind of language...
