Reading a Stream in Java

Parent.java

  StringBuilder sb = new StringBuilder();
		Runtime rt = Runtime.getRuntime();
  
  //You need to use this!
		String current =  System.getProperty("java.class.path");
		  System.out.println("Current dir:"+current);
		 
//Make sure to use -classpath flag
		Process proc = rt.exec("java -classpath " + current + " Memory");

		InputStream is = proc.getInputStream();

		Scanner sc = new Scanner(is);
			 
		while(sc.hasNext())
		{
			String line = sc.nextLine();
			for (int i=0; i<line.length(); i++)
			{
				System.out.print(line.charAt(i));
