Java mein “comments in java” ek aham hissa hain jise code likhte waqt istemal kiya jaata hai. Comments code mein notes ki tarah hote hain jo code ke functionality, logic, ya documentation ko explain karne mein madad karte hain. Yeh code ke readability ko badhate hain aur dusre developers ko code ko samajhne mein madad karte hain.

Java mein do prakar ke comments hote hain:

1. Single-line Comments

Single-line comments double slashes (//) ke saath shuru hote hain. In comments ko likha gaya text sirf ek line ke liye hota hai aur us line ke baad kuch bhi execute nahi hota.

Example:

// Yeh ek single-line comment hai. Is line ke baad ka code execute nahi hoga.
int x = 5; // Yeh bhi ek single-line comment hai.

2. Multi-line Comments

Multi-line comments slash-star (/*) se shuru hote hain aur star-slash (*/) se samapt hote hain. In comments mein multiple lines ka text likha ja sakta hai aur yeh kisi bhi number ke lines ko comment karne ke liye istemal kiya ja sakta hai.

Example

/*
Yeh ek multi-line comment hai.
Ismein multiple lines ka text likha ja sakta hai.
Koi bhi code execute nahi hoga in lines ke beech.
*/
int y = 10; // Yeh ek code line hai.

Comments ka istemal code ko explain karne, debugging mein madad karne, aur dusre developers ke liye code ko samajhne mein madad karne ke liye kiya jaata hai.
