ThreadGroup Class setMaxPriority() method

  • setMaxPriority() method is available in java.lang package.
  • setMaxPriority() method is used to assign a maximum priority of this thread group and there is no effect on higher priority threads already exists in this ThreadGroup.
  • setMaxPriority() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • setMaxPriority() method may throw an exception at the time of assigning a priority of this ThreadGroup.
    SecurityException – This exception may throw when the current thread is not permitted to update this thread group.


    public final void setMaxPriority(int prior);


  • int prior – represents the new priority of this thread group.

Return value:

The return type of this method is void – it returns nothing.


// Java program to demonstrate the example 
// of void setMaxPriority(int prior) method of ThreadGroup 

public class SetMaxPriority implements Runnable {
    public static void main(String[] args) {
        SetMaxPriority max_pri = new SetMaxPriority();

    public void setPrio() {
        try {
            // Create two thread group and the named are base
            // and derived
            ThreadGroup base = new ThreadGroup("Base ThreadGroup");
            ThreadGroup derived = new ThreadGroup(base, "Derived ThreadGroup");

            // By using setMaxPriority() method is to set the
            // maximum priority for both the thread group
            // 7 for base and 5 for derived thread group


            // create two threads
            Thread th1 = new Thread(base, this);
            Thread th2 = new Thread(derived, this);

            //By using getName() method is to retrieve the
            // name of the thread th1
            System.out.println(th1.getName() + " " + "begins.....");

            // By using start() method is to start its execution 
            // of thread th1

            // By using getName() method is to retrieve the
            // name of the thread th2
            System.out.println(th2.getName() + " " + "begins.....");

            // By using start() method is to start its execution 
            // of thread th2

            // By using join() method is to wait the current
            // thread till complete execution of another
            // thread
        } catch (InterruptedException ex) {

    // Override run()
    public void run() {
        for (int k = 0; k < 100; ++k)
        System.out.println(Thread.currentThread().getName() + " " + "ends.....");


Thread-0 begins.....
Thread-0 ends.....
Thread-1 begins.....
Thread-1 ends.....
