The “Cannot find symbol” error in Java is a common stumbling block for beginners and experienced developers alike. This compiler error occurs when the Java compiler encounters a reference to a symbol – like a variable, method, or class – that it c
错误的意思不能解析class LendHandler 这个类，可能是的环境变量没有设置好，页可能是类本身有问题，先检查一下你的环境变量，如果没错就是类写的有问题
显示无法找到symbol的原因一般是找不到对应的jar包,在非maven工程下需要手动导入jar包: 对于maven工程无法找到的原因一般是分两种:类对应的依赖没有加载进来、编译器自身的设置和缓存问题 第一步:检查工程内是否已有用到的jar包--》已有跳入第二步,未有跳入第二步 第二
