在android studio Java中计算

public class Calculator {
    
    public int add(int num1, int num2) {
        return num1 + num2;
    }
    
    public int subtract(int num1, int num2) {
        return num1 - num2;
    }
    
    public int multiply(int num1, int num2) {
        return num1 * num2;
    }
    
    public int divide(int num1, int num2) {
        if (num2 != 0) {
            return num1 / num2;
        } else {
            throw new ArithmeticException("Division by zero is not allowed.");
        }
    }
    
    // 可以根据需要添加其他计算方法
}

Calculator calculator = new Calculator();

int result = calculator.add(2, 3);
