Calculator (Switch)
Calculator Program using Switch Case in Java
A simple calculator that uses switch case to pick the operation.
Java Program
int a = 10, b = 5; char op = '*';
switch (op) {
case '+': System.out.println(a + b); break;
case '-': System.out.println(a - b); break;
case '*': System.out.println(a * b); break;
case '/': System.out.println(b != 0 ? a / b : "Cannot divide"); break;
default: System.out.println("Invalid");
}Output
50
How it Works
- switch selects the operation based on the operator character.
- Division checks for divide-by-zero first.
Summary
- A simple calculator that uses switch case to pick the operation.

कैसे काम करता है
- switch operator character के आधार पर operation चुनता है।
- Division पहले divide-by-zero जाँचता है।
