Can you use deprecated methods?
Same for Java’s @Deprecated – you can still use the method, but at your own risk – in future, it might have better alternatives, and might not even be supported. If you are using code that is deprecated, it’s usually fine, as long as you don’t have to upgrade to a newer API – the deprecated code might not exist there.
What method in the Thread class do you call to cease the execution of the thread of a certain amount of time?
sleep(): causes the thread to definitely stop executing for a given amount of time; if no other thread or process needs to be run, the CPU will be idle (and probably enter a power saving mode).
Which state is entered once a thread is created?

How does a new thread is created?
There are two ways to create a new thread of execution. One is to declare a class to be a subclass of Thread; The other way to create a thread is to declare a class that implements the Runnable interface.

What are different states in life cycle of thread?
Life cycle of a Thread (Thread States) According to sun, there is only 4 states in thread life cycle in java new, runnable, non-runnable and terminated. There is no running state. But for better understanding the threads, we are explaining it in the 5 states. The life cycle of the thread in java is controlled by JVM.
How can you ensure all threads that started from Main?
Answer. We use join() methodto ensure all threads that started from main must end in order in which they started and also main should end in last.
What is normal priority of thread?
Default priority of a thread is 5 (NORM_PRIORITY). The value of MIN_PRIORITY is 1 and the value of MAX_PRIORITY is 10.
What are thread priorities?
This algorithm schedules threads based on their priority relative to other runnable threads. When a Java thread is created, it inherits its priority from the thread that created it. You can also modify a thread’s priority at any time after its creation using the setPriority method.
How can the priority of thread be set?
By default, a thread inherits the priority of its parent thread. You can increase or decrease the priority of any thread with the setPriority method. You can set the priority to any value between MIN_PRIORITY (defined as 1 in the Thread class) and MAX_PRIORITY (defined as 10). NORM_PRIORITY is defined as 5.
What is priority assigned to all Java threads by default?
Background Information: Java Threads setPriority(int) to assign priorities to Java threads. The default priority of a Java thread is NORM_PRIORITY . (A Java thread that doesn’t explicitly call setPriority runs at NORM_PRIORITY .) A JVM is free to implement priorities in any way it chooses, including ignoring the value.
