def map = [
P1: [name:"Jerry", age: 42, city: "New York"],
P2: [name:"Long", age: 25, city: "New York"],
P3: [name:"Dustin", age: 29, city: "New York"],
P4: [name:"Dustin", age: 34, city: "New York"]];
我有上面的地圖，我想根據年齡對地圖進行排序
uj5u.com熱心網友回復：
你可以這樣做：
def map = [
P1: [name:"Jerry", age: 42, city: "New York"],
P2: [name:"Long", age: 25, city: "New York"],
P3: [name:"Dustin", age: 29, city: "New York"],
P4: [name:"Dustin", age: 34, city: "New York"]]
def sortedByAge = map.sort { entry ->
entry.value.age
}
