BlueJ

Question

On my machine I am currently running Oracle 9i and BlueJ (Java). I believe Oracle installs its own JDK, BlueJ also does this.
When I am trying to run BlueJ, and I am trying to edit the code in a class, it doesnt let me open it, I believe it uses the wrong JDK (Oracle) and not BlueJ's.
Is it possible for me to select the right JDK? and how?

i need help. i need to know how to use arrays to store user input. I have so far, the following code.
import java.io.*;
import java.util.Scanner;
import java.util.*;
public class ReadConsole
public static void main(String[] args)
Scanner input = new Scanner(System.in);
System.out.println("Menu System - Please enter your choice");
System.out.println("Option 1");
System.out.println("Option 2");
System.out.println("Option 3");
for(int i = 0; i < 1; i++){
int num = input.nextInt();//
if(num==1){
System.out.println("Option 6");}
else if(num==2){
System.out.println("Option 7");}
else if(num==3){
System.out.println("Option 8");}
else{
System.out.println("Try again");
i = 0;
}
