Program Run Result:

Program Design ideas: First define a series of variables, count is used to represent the number of input integers, next is used to hold the input of each number, sum to hold 4 integers, and define a scanner object, Scanner is a simple text scanner that uses regular expressions to parse basic types and strings to read integers entered by the user. The Nextint () method of the class is called in the Recycle statement, the integer entered by the user is read, placed in next, and then added in sum, and finally 4 integers are evaluated through a loop.
