parameter in java

Today what i learned in class

• define parameter- A parameter in Java is a variable that is declared in a method or constructor definition and is used to accept input values when the method is called

Simple Meaning

• It is like a placeholder for data.
• It lets you pass information into methods.7

class Example {
    // 'a' and 'b' are parameters (formal parameters)
    static int add(int a, int b) {
        return a + b;
    }

    public static void main(String[] args) {
        // 5 and 10 are arguments (actual parameters)
        int result = add(5, 10);
        System.out.println("Sum: " + result);
    }
}

• Parameters → int a, int b (declared in method definition)
• Arguments → 5, 10 (values passed while calling the method)

Why Are Parameters Used?

• To pass data into a method.
• To make methods reusable with different values.
• To avoid repeating the same code with different hardcoded values.
