Overview I have created a simple calculator program in Java that can perform basic operations like addition, subtraction, multiplication, and division. These operations are performed using a switch case statement in Java. 자바로 간단한 계산기 프로그램을 만들었다. 덧셈, 뺄셈, 곱하기, 나누기와 같은 기본 연산을 수행할 수 있다. 이 연산은 자바의 switch case문으로 구현된다. Program Description The user should input two numbers. After that the program will ..

The scanner class consists next() and nextLin() methods. next() Method: The next() method in java is present in the Scanner class and is used to get the input from the user. In order to use this method, a Scanner object needs to be created. This method can read the input only until a space (" ") is encountered. In other words, it finds and returns the next complete token from the scanner. Exampl..
