for (Employee employee : list) {
}
怎么比较两个employee的id~
------解决方案--------------------
- Java code
for (int i = 0; i < list.size(); i++) {
Employee e1 = (Employee) list.get(i);
for (int j = i + 1; j < list.size(); j++) {
Employee e2 = (Employee) list.get(j);
// 数值型
if (e1.id == e2.id) {
// TODO
}
// 非数值型
if (e1.id.equals(e2.id)) {
// TODO
}
}
}
