Java是不是强制try语句了
netbeans7.1
我用URL类提示我要用Try语句，写个System.in.read()也要用Try语句。疯了
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - unreported exception java.io.IOException; must be caught or declared to be thrown
at hashdos.HashDos.main
[解决办法]
不想用try 把他抛出去 在方法后面写throws Exception {
建议使用try catch 块
[解决办法]
must be caught or declared to be thrown，可以try可以throws
