我阅读文本。我的文字是这样的

AYSE;SERDAR-9.8;EMRE-5.2;AYTAC-3.3
FATMA;OYTUN-8.8;ORKUN-7.5;ONUR-5.4;UMUT-4.4;BERK-3.3;CAN-3.2
DERYA;VELI-7.7;ALI-6.5;SUAT-6.0;YAVUZ-5.0;OYTUN-4.2;ORKUN-3.1
DILARA;DOGUS-8.8;VELI-7.4;ALI-6.5;SUAT-5.5;YAVUZ-3.1
BEGUM;SUAT-6.6;YAVUZ-5.1;OYTUN-4.3;ORKUN-4.0
BERIL;CANER-8.7;DOGUS-7.5;VELI-6.2;ALI-6.1;SUAT-5.8;YAVUZ-4.8;OYTUN-4.0
FUNDA;ORKUN-9.7;ONUR-8.3;UMUT-7.2;BERK-6.5;CAN-5.5
ISIL;AYTAC-8.3;CANER-7.4;DOGUS-6.5;VELI-5.5;ALI-5.4;SUAT-4.4;YAVUZ-4.0;OYTUN-3.9;ORKUN-3.5;ONUR-3.4;UMUT-3.2;BERK-3.1;CAN-3.0
ELIF;EMRE-7.4;AYTAC-6.1

我不能将“u.eleman”和“u.uyum”值添加到“treeset tSU”。当我在 tSU TREESET 中看不到它们时，它会给出内存地址。我想将它们全部添加到树集中。我怎么能这样做..请帮忙

当我在 tSU TREESET 中看不到它们时，它会给出内存地址。

不，它不打印内存地址。它以十六进制打印@对象的类名、an 和哈希码 - 这是Object.toString()默认情况下所做的。

如果您希望Uyum以不同方式打印对象，请覆盖toString()您的类中的方法Uyum。
