实验代码

System.out.println("---------------------------java.class.path----------------------------");

for(String location : System.getProperty("java.class.path").split(";")) {

System.out.println(location);

}

System.out.println("---------------------------java.ext.dirs----------------------------");

for(String location : System.getProperty("java.ext.dirs").split(";")) {

System.out.println(location);

}

System.out.println("-----------------------sun.boot.class.path--------------------------------");

for(String location : System.getProperty("sun.boot.class.path").split(";")) {

System.out.println(location);

}

测试结果
