intnumber=scanner.nextInt(); 1. 步骤三:判断用户输入的数字是否在"longjava范围"内 在这一步中,我们需要判断用户输入的数字是否在"longjava范围"内。"longjava范围"是指在Java中long类型的取值范围,即-9223372036854775808到9223372036854775807。 booleanisInRange=(number>=Long.MIN_VALUE&&number<=Long.MAX_VALUE...
Learn how to use the hasNextLong method in Java's Scanner class to check if the next token can be interpreted as a long value.
