Hi,
I am new to java, i faced one interview question "How to sort the list of integers Array by using plane java code",
please help me on this answer.

Note: dont use any Collections.sort() method.

Ex: int a[]={3,5,2,1,7,4}
sort this array by using plane java code.

Thanks,
-------

Well, since Collections.sort() is itself just "plain" Java code--that is, no different from something any Java programmer could write himself--you would write a sort method that operates similarly to Collections.sort().

If you didn't study sorting algorithms in your CS education, or don't remember them, you can google for sorting algorithms.
