5 kotlin之 try catch

kotlin的try catch比Java更简洁面料采用,使用更方便

 val value = "10a"var out: Int? = null//错误处理try {out = Integer.parseInt(value)} catch (e: NumberFormatException) {println("NumberFormatException")println(e.message)} catch (e: Exception) {println("Exception")println(e.message)} finally {println("out is $out")}//赋值处理var outPut = try {Integer.parseInt(value)} catch (e: Exception) {-1}println("output is $outPut")
