为什么在 eclipse for linux 运行不了java，显示Permission denied

Question

编译HelloWorld
public class HelloWorld {

public static void main(String[] args) {
    System.out.println("Hello World!!");

}

}

出现一个对话框：

Exception occurred executing command line.
Cannot run program "/home/master/linuxsoftware/eclipse/jre/bin/java" (in directory "/home/master/DevelopmentCode/eclipseProject/HelloWorld"): error=13, Permission denied

Answer 1

ls -l /home/master/linuxsoftware/eclipse/jre/bin/java
查看java文件的执行权限，和用户权限。
