下列代码输出为( ) public class ReferencesTest { static class Student { private String name; } public static void main(String[] args) { Student studentA = new Student(); studentA.name = “aaa”; Student studentB = new Student(); studentB.name = “bbb”; setName(studentA.name, “ccc”); setName(studentB, “ccc”); System.out.println(studentA.name + “, ” + studentB.name); } private static void setName(String name, String newName) { name = newName; } private static void setName(Student student, String newName) { student.name = newName; } }

下列代码输出为( ) public class ReferencesTest
{
static class Student {
private String name; }
public static void main(String[] args) {
Student studentA = new Student();
studentA.name = “aaa”;
Student studentB = new Student();
studentB.name = “bbb”;
setName(studentA.name, “ccc”);
setName(studentB, “ccc”); System.out.println(studentA.name + “, ” + studentB.name);
}
private static void setName(String name, String newName) {
name = newName; }
private static void setName(Student student, String newName) {
student.name = newName; }
}
为什么第一个没有变啊
