JDK ka full form "Java Development Kit" hai. Yeh ek software development environment hai jo Java applications banane ke liye use hota hai. JDK mein kuch important components hote hain, jinki madad se Java developers apne applications develop, compile aur run kar sakte hain.
In components mein include hain:
1. JRE (Java Runtime Environment): JRE woh environment hai jisme Java programs run hote hain. Yeh JVM (Java Virtual Machine) aur class libraries ko include karta hai.
2. JVM (Java Virtual Machine): JVM woh virtual machine hai jo Java bytecode ko execute karti hai. Yeh platform-independent hai, matlab aap ek hi Java program ko alag-alag operating systems par run kar sakte hain bina code ko badle.
3. Compiler (javac): Javac compiler Java source code (.java files) ko bytecode (.class files) mein convert karta hai.
4. Java Archiver (jar): Jar tool Java applications aur libraries ko package karne ke liye use hota hai.
5. Documentation Generator (javadoc): Javadoc tool source code se HTML documentation generate karta hai.
6. Debugger (jdb): Jdb tool Java programs ko debug karne ke liye use hota hai.
JDK mein in sabhi tools ke alawa aur bhi kai utilities aur libraries hoti hain jo Java development ko asaan aur efficient banati hain. JDK ko install karne ke baad, aap command line ya Integrated Development Environment (IDE) ka use karke Java programs likh sakte hain, compile kar sakte hain aur execute kar sakte hain.
