Java通过反射设置私有变量

public class PrivateTest {
    private String name = "hello";

    public String getName() {
        return name;
    }
}

import java.lang.reflect.Field;

public class ReflectionTest {
    public static void main(String[] args) throws Exception {
        PrivateTest pt = new PrivateTest();

        Class<PrivateTest> clazz = PrivateTest.class;

        Field field = clazz.getDeclaredField("name");
        field.setAccessible(true);
        field.set(pt, "world");
        field.setAccessible(false);

        System.out.println(pt.getName());
    }
}
