编译运行可得
Code:
publicclassHelloWorld{
publicstaticvoidmain(String args[]){
System.out.println("Hello! World");
System.out.println(System.getProperty("java.library.path"));
}
}
结果：
Hello! World

path 路径，是java编译时需要调用的程序(如java，javac等)所在的地方 。
classpath 类的路径，在编译运行java程序时，如果有调用到其他类的时候，在classpath中寻找需要的类。
______________________________
一般这个路径是你的java项目引用的jdk下的jre目录的bin目录。java/jdk/jre/bin.
