应该是java的问题吧，但不知道怎么解决，java重装了几次,依旧这样，弄了一天了，求大佬帮助啊

你调内存了吗？建议2048file:///D:/Documents/Tencent%20Files/1269045526/FileRecv/%E6%9C%80%E6%96%B0java8%EF%BC%8864%E4%BD%8D%EF%BC%89.exe

又有丢文件的了，你吃饭的碗缺一半可以用？使用起动器重新补全文件
你百度下NoClassDefFoundError报错会咋地，硬要怪java问题，碗缺一半重换筷子有毛用，这就像排插坏了换电表，根本没打上去

可以选择设置一下内存大小，根据自己机子配置，选最优内存
