or sunn chita he kha daa………………

Java ke keywords ko “reserved words” bhi kaha jata hai. Keywords kuch khaas shabdon ko represent karte hain jo code ke liye ek prakar se key ka kaam karte hain. Ye Java dwara pehle se define kiye gaye shabd hote hain, isliye inka istemal kisi bhi variable, object name, ya class name ke roop mein nahi ho sakta.

Java ke kuch keywords ya reserved words ki ek list niche di gayi hai:

• abstract: Java abstract keyword ka istemal abstract class declare karne ke liye hota hai. Ek abstract class ek interface ki implementation de sakti hai aur isme abstract aur non-abstract methods hote hain.
• boolean: Java boolean keyword ka istemal ek variable ko boolean type declare karne ke liye hota hai. Isme sirf True aur False values ho sakti hain.
• break: Java break keyword ka istemal loop ya switch statement ko todne ke liye hota hai. Ye program ki current flow ko specified conditions par tod deta hai.
• byte: Java byte keyword ka istemal 8-bit data values ko hold karne ke liye hota hai.
• case: Java case keyword switch statements ke saath istemal hota hai, text ke blocks ko mark karne ke liye.
• catch: Java catch keyword try statements se generate hone wale exceptions ko catch karne ke liye hota hai. Iska istemal try block ke baad hi hota hai.
• char: Java char keyword ka istemal 16-bit unsigned Unicode characters ko hold karne ke liye hota hai.
• class: Java class keyword ka istemal class declare karne ke liye hota hai.
• continue: Java continue keyword ka istemal loop ko continue karne ke liye hota hai. Ye program ki current flow ko specified condition par continue karta hai.
• default: Java default keyword switch statement mein default block of code ko specify karne ke liye hota hai.
• do: Java do keyword control statement mein loop declare karne ke liye hota hai. Ye program ke kuch hisse ko kai baar iterate kar sakta hai.
• double: Java double keyword ka istemal 64-bit floating-point numbers ko hold karne ke liye hota hai.
• else: Java else keyword if statement mein alternative branches ko indicate karne ke liye hota hai.

… aur aise hi bahut se aur keywords hote hain. Aap inhe apne Java programs mein istemal kar sakte hain.
