java 创建匿名对象 类似于c# 中的 new { a:"aaa",b:"bbb"};

1 创建匿名对象
Object myobj = new Object() {
public final boolean success = true;
}

2 字面量方式初始化mapMap<String, String> myMap = new HashMap<>() {{

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

}
3 初始化数组

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