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 } } }
