我只是想从列表中删除重复的元素.为此,我写了一个POJO类Student:
class Student{
private String roll;
private String name;
public Student(String roll, String name) {
this.roll = roll;
this.name = name;
}
@Override
public boolean equals(Object obj) {
Student st = (Student) obj;
return st.getRoll().equals(roll);
}
public String getRoll() {
return roll;
}
public void setRoll(String roll) {
this.roll = roll;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return roll ;
}
} …我是Javascript的新手,最近知道setTimeout设置为0 millis的用法.我正在尝试实现它,但没有得到预期的结果.根据我的知识,它必须等到所有事件都完成但它没有表现得很好.请告诉我我错过了什么或我错在哪里.

我期待着类似的东西
