Compile Java In Xcode

Recently I start to read Algorithm 4th which uses Java to express the thought of algorithm. However , I had not even write a helloworld.java file until I opened this book.

I found some steps to compile java in Xcode and I make of note of these steps.

1. Install java and make sure there are bin files named java and javac in your /usr/bin/ ;
2. Open Xcode ;
3. New project — Other — External Build System;
4. Set the build tool to /usr/bin/javac;

public class helloWorld
  {
   public static void main(String[] args)
   {
    System.out.println("hello world");
   }
 }

5. Clicking the “Run >” button should at least compile your file now, but it is not really running . However , you can find a compiled file named <JavaFileName>.class in the same place if things go right;

6. And then we focus on the menu and select Product — Scheme — Edit Scheme , select Executable — other… and use command+shift+G to located the /usr/bin/java ,at the same time you should uncheck the Debug Executable if you don’t need that;

7. Select Argument tab and add argument and variable as follow(You can add common arguments which you like to pass on launch);

8. Now you can enjoy the automatic compiling and running Java program code with Xcode by simple hitting command + R.
