method with a variable number of parameters

Fri Dec 12, 2008 9:56 pm

In java J2SE0.5 you can now make a function with a variable number of paramters. The rules to do that is :

- Only varaible paramter list only .
- varaible paramter list must apper in the last inside the parentheses of the function.
- defined as : type followed by three dots and the name .

And example about method with a variable number of parameters.
Code:
import java.io.*;
class MyClass {
public void printStuff(String greet, int... values) {
for (int v : values ) {
System.out.println( greet + ":" + v);
}
}
}
class VarargTest {
public static void main(String[] args) {
MyClass mc = new MyClass();
mc.printStuff("Hello", 1);
mc.printStuff("Hey", 1,2);
mc.printStuff("Hey you", 1,2,3);
}
}
