实在没分了，请问下这个程序，获取控制台运行java程序结果，但是无内容，怎么破？

[我想飞走]

	
public static void main(String[] args) throws Exception {

		String path = "c://Test.java";    
		Runtime run = Runtime.getRuntime();    
		StringBuilder result = null;  
	
		run.exec("cmd /k javac   " +path);//进行编译，获得成功
		Process process = run.exec("cmd /k java Test");//运行，但是下面无法获得输出
	
		InputStream is = process.getInputStream();
		BufferedReader br = new BufferedReader(new InputStreamReader(is));
		while(br.readLine() != null){
			System.out.println(br.readLine());
		}
	}

查看生成了Test.class了么？

while(br.readLine() != null){ System.out.println(br.readLine()); } 改成 String str=""; while((str=br.readLine() )!= null){ System.out.println(str); } br.readLine()这句就已经读出来了，再读怎么可能有

引用 2 楼 AA5279AA 的回复:

while(br.readLine() != null){ System.out.println(br.readLine()); } 改成 String str=""; while((str=br.readLine() )!= null){ System.out.println(str); ……

正解
