there may be other situations in which two threads have the same priority. The Java thread scheduler handles all of the processing for thread management. Consider the following example to see what happens if two threads have the same
Every Thread in java has a priority. It may be the default priority assigned by the JVM or a customized priority explicitly provided by the programmer. The valid range of thread Priority is between 1 to 10, where 1 is the minimum and 10 is the maximum priority. The default priority is 5...
In general, at any time, the highest priority thread is running. But sometimes, the thread scheduler might choose low-priority threads for execution to avoid starvation. 4. Knowing and Changing a Thread’s Priority Java’s Thread class provides methods for checking the thread’s priority and fo...

Once we start any thread, it’s execution depends on the OS implementation of time slicing and we can’t control their execution. However we can set threads priority but even then it doesn’t guarantee that higher priority thread will be executed first. Run the above program multiple times ...
