assertion example

What will happen if you attempt to compile following code with JDK1.4 with assertions enabled

public class Bbridge{
    int iRunningTotal=0;
    public static void main(String argv[]){
        Bbridge bb = new Bbridge();
        bb.go(argv[0]);
    }  
    public void go(String s){
        int i = Integer.parseInt(s);
        setRunningTotal(i);            
        assert (iRunningTotal > 0): getRunningTotal();
    }
    public String getRunningTotal(){
        return "Value of iRunningTotal "+iRunningTotal;
    }
    public int setRunningTotal(int i){
        iRunningTotal+=i;
        return iRunningTotal;
    }
}
1) Compile time error, getRunningTotal does not return a boolean
2) Compile time error malformed assert statement
3) Compilation and no output given a command parameter of 1
4) Compilation and assert error given a command parameter of 0

I was trying above example from link

http://www.jchq.net/certkey/0205certkey.htm

did not understand how to run and get output while running in eclipse ide.How to enable assertion and run this example.

I was trying to understand the output.


 Any links, ideas, resources,sample code highly appreciated. thanks in advance.
