String to Number with Integer.parseInt()

Easy

Problem Description

String to Number with Integer.parseInt()

In this problem: You will create a program that converts strings to integers using the Integer.parseInt() method and outputs calculation results.

Learning Objective: Understand string-to-number conversion using the Integer wrapper class parse method

Overview

In Java, the string "123" and the number 123 are different types. To use a string as a number in calculations, you need to convert it with Integer.parseInt(). Passing an unconvertible string will cause an exception.

Specifications

  • Convert 3 numeric strings ("100", "250", "50") to int
  • Calculate and print the sum
  • Calculate and print the average (integer division)
  • Print Integer.MAX_VALUE and Integer.MIN_VALUE

Output Format

Values: 100, 250, 50
Sum: 400
Average: 133
Max int: 2147483647
Min int: -2147483648
