javaee-List<Map<String,Object>>中的id為什麼無法和String的id匹配?(有圖)

List<Map<String,Object>>中的id為什麼無法和String的id匹配?(有圖)

最佳回答：

public boolean equals(Object anObject) {
if (this == anObject) {
return true;
}
if (anObject instanceof String) {
String anotherString = (String)anObject;
int n = count;
if (n == anotherString.count) {
char v1[] = value;
char v2[] = anotherString.value;
int i = offset;
int j = anotherString.offset;
while (n-- != 0) {
if (v1[i++] != v2[j++])
return false;
}
return true;
}
}
return false;
}
