我需要在Mac上找到安装Firefox应用程序的目录,我运行终端命令:
find / -name Firefox.app 2>/dev/null
现在我需要在java程序中运行相同的命令,我的代码是:
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class kill{
public static void main(String[] args) throws Exception{
String cmds[] = {"find","/","-name","Firefox.app"};
Process p = Runtime.getRuntime().exec(cmds);
p.waitFor();
//int exitVal = p.waitFor();
//System.out.println("Process exitValue:" + exitVal);
BufferedReader reader =
new BufferedReader(new InputStreamReader(
p.getInputStream()));
String line = reader.readLine();
while (line != null) {
line = reader.readLine();
System.out.println(line);
}
}
}
但它并没有让我回归。任何人都可以告诉我这里有什么问题..任何帮助将不胜感激
答案 0 :(得分:0)
循环中存在逻辑错误。应该是这样的:
String line = reader.readLine();
while (line != null) {
System.out.println(line);
line = reader.readLine();
}
尽管如此,Firefox总是应该在/ Applications中。
