1.list转string 命令:''.join(list) 其中,引号中是字符之间的分割符,如“,”,“;”,“\t”等等 如: list = [1, 2, 3, 4, 5] ''.join(list) 结果即为:12345 ','.join(list) 结果即为:1,2,3,4,5 str=[] #有的题目要输出字符串,但是有时候list更好操作,于是可以最后list转string提交 ...
String str = Joiner.on(",").join(list); 6、String自带join方法可以实现 String str= String.join(",", list); 原来String自己就有List集合用逗号拼接成字符串的api,这个方法应该是最牛的了! 总结 Java List集合用逗号拼接成字符串的6种方法,当前你也可以将逗号换成任意你想要的符号,以上方法你觉得哪一...
