If you do not want your variable shared, then do not use a global variable (you probably mean static in Java). Create a new field with a new object initialized when your thread starts. Example: public class HelloThread extends Thread {. private MyObject myThreadVariable; // This is the thread-local variable.Java threading is the concept of using multiple threads to execute different tasks in a Java program. A thread is a lightweight sub-process that runs within a process and shares the same memory space and resources. Threads can improve the performance and responsiveness of a program by allowing parallel execution of multiple tasks.Java Thread Example. Every java application has at least one thread - main thread. Although there are so many other java threads running in background like memory management, system management, signal processing etc. But from application point of view - main is the first java thread and we can create multiple threads from it.Types of Threads in Java.
