回答: 使用try catch快捷方式的自动化操作的快捷键是Ctrl+Alt+T。\[1\]这个快捷键可以用于包裹代码块,并选择try catch语句。同时,这个快捷键也可以用于其他方法,比如if、if/else、while、do/while等。\[1\]在try catch语句中,try块用于包含可能会抛出异常的代码,catch块用于捕获并处理异常,finally块用于无论是否发生异常都会执行的代码。\[2\]在Scala中,try catch finally的示例代码如下:
object ExceptionCatchDemo extends App {
def testTryCatchFinally: Int = {
try {
throw new Exception()
} catch {
case _ => 2
} finally {
3
}
}
println(testTryCatchFinally)
}
这段代码中,try块抛出了一个异常,catch块捕获并返回2,finally块始终会执行并返回3。\[3\]希望这些信息对你有帮助!
