java 創建匿名對象及聲明map list時初始化

java 創建匿名對象 類似於c# 中的 new { a:"aaa",b:"bbb"};

 

1 創建匿名對象
Object myobj = new Object() {
  public final boolean success = true;
}

2 字面量方式初始化map

Map<String, String> myMap = new HashMap<>() {{

 put("a", "b"); put("c", "d"); }};

}
3 初始化數組

var refEntityIDs = new ArrayList<String>(Arrays.asList(
    　　　　 BalanceConst.BEIDVoucherOptFail,
            BalanceConst.BEIDAccountingDocument,
            BalanceConst.BEIDAccDocOptPreTbl
));
