孙鑫JAVA从入门到精通配套练习程序。所有程序都实际运行过

import java.io.*;
class RuntimeTest
{
	public static void main(String[] args)
	{
		Runtime rt = Runtime.getRuntime();
		System.out.println(rt.freeMemory());
		System.out.println(rt.totalMemory());
		try
		{
			Process p = rt.exec("java ArrTest");
			/*InputStream is = p.getInputStream();
			int data;
			while((data=is.read()) != -1)
			{
				System.out.print((char)data);
			}*/
		}
		catch(IOException ex)
		{
			ex.printStackTrace();
		}
	}
