1) How to find 5 most frequent apprearance workds in a words array? what if the size of the array is so big that we only need ot find approximate 5 top popular words?
2) Assume speed is more important than storage. How do you count the number of bits that will set in 32 bit integer?

Please help. Thanks!

Programming Diversions is for... diversions. Java Questions, (even ones that sound like homework) should be asked in the other forums.

I'll move it to the Java in General (beginner) forum for you.

Piggy Jing Piggy Jing,

Welcome to the Ranch.

Perhaps StringUtils will help you get what you want. You might also want to browse thru the ArrayUtils class in the same package to see if it helps. Let us know if it did.

Are homework sets out all ready? I thought everyone was still on break.
