Sorting an array of Objects

[blues77]

Hello,

I was wondering if anyone knew of any Java native API method that would allow me to sort an Array of objects based on a integer instance variable in the objects. For instance, say I had a class called ABC which contained an integer instance variable called x. Each instance of class ABC has a value assigned to x and I want to sort the Array of ABC objects in order based on the value of x. If anyone has any suggests I would appreciate hearing from you.

Thanks

Java native API

What do you mean by this exactly ? Do you mean a JNI interface to a C/C++/Assembler method or something else ?

Perhaps he means Arrays.sort (array)?
See javadocs for java.util.Arrays.

I remember having answered this post before.

You need to implement Comparable.
