Let’s discuss the question: how to call two methods simultaneously in java. We summarize all relevant answers in section Q&A of website 1st-in-babies.com in category: Blog MMO. See more related questions in the comments below.
Can you use two methods at once Java?
Yes, we can define multiple methods in a class with the same name but with different types of parameters. Which method is to get invoked will depend upon the parameters passed.
How do you call two methods parallel in Java?
…
Do something like this:
- For each method, create a Callable object that wraps that method.
- Create an Executor (a fixed thread pool executor should be fine).
- Put all your Callables in a list and invoke them with the Executor.

Can we run two threads simultaneously in Java?
Overview. Multi-thread programming allows us to run threads concurrently, and each thread can handle different tasks. Thus, it makes optimal use of the resources, particularly when our computer has a multiple multi-core CPU or multiple CPUs. Sometimes, we’d like to control multiple threads to start at the same time.
Can a class have two methods with the same name in Java?
What is Overloading? For convenience, Java allows you to write more than one method in the same class definition with the same name. For example, you can have two methods in ShoppingCart class named computeCost. Having two or more methods named the same in the same class is called overloading.
Is it possible to have two methods?
you can create two methods with the same args and method name, but diffrent return values only.
Can we run two threads simultaneously?
Within a process or program, we can run multiple threads concurrently to improve the performance. Threads, unlike heavyweight process, are lightweight and run inside a single process – they share the same address space, the resources allocated and the environment of that process.
How do you call parallel in Java?
- Add @Async annotation to the function you want to parallelize getCountriesByLanguage and getCountriesByRegion.
- Change the return type of the function by CompletableFuture<List<Country>>
What is multithreading in Java?
Multithreading is a Java feature that allows concurrent execution of two or more parts of a program for maximum utilization of CPU. Each part of such program is called a thread. So, threads are light-weight processes within a process.
Can we have two methods in a class with the same name?
Two or more methods can have the same name inside the same class if they accept different arguments. This feature is known as method overloading. Method overloading is achieved by either: changing the number of arguments.
Can we write two main methods Java class?
From the above program, we can say that Java can have multiple main methods but with the concept of overloading. There should be only one main method with parameter as string[ ] arg.

How do you call a class inside another class?
Inner classes
To instantiate an inner class, you must first instantiate the outer class. Then, create the inner object within the outer object with this syntax: OuterClass. InnerClass innerObject = outerObject.
Can 2 threads perform write operations on same ConcurrentHashMap object simultaneously?
Having two threads that change the map at the very same point time is not possible. Because the code within that ConcurrentHashMap will not allow two threads to manipulate things in parallel!
What is difference between multitasking and multithreading?
Multitasking lets the CPU perform various tasks simultaneously (threads, process, program, task), while multithreading helps in the execution of various threads in a single process simultaneously.
What is multithreading OS?
Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the programming running in the computer.
Can two methods have the same signature in Java?
But you cannot declare two methods with the same signature and different return types. It will throw a compile-time error. If both methods have the same parameter types, but different return types, then it is not possible. Java can distinguish the methods with different method signatures.
Is it possible to declare two or more methods with the same name within a class if yes what are the rules to be followed give an example?
You cannot declare more than one method with the same name and the same number and type of arguments, because the compiler cannot tell them apart. The compiler does not consider return type when differentiating methods, so you cannot declare two methods with the same signature even if they have a different return type.
Is overriding possible in Java?
In Java, method overriding occurs when a subclass (child class) has the same method as the parent class. In other words, method overriding occurs when a subclass provides a particular implementation of a method declared by one of its parent classes.
How is multithreading possible?
In a multithreaded process on a single processor, the processor can switch execution resources between threads, resulting in concurrent execution. Concurrency indicates that more than one thread is making progress, but the threads are not actually running simultaneously.

Is multithreading concurrent or parallel?
Multithreading on multiple processor cores is truly parallel. Individual microprocessors work together to achieve the result more efficiently. There are multiple parallel, concurrent tasks happening at once.
How do you make 2 threads run one after another?
To execute threads one after another it needs to be synchronized. wait notify notifyAll is useful. This is the famous interview question for the beginners, Write a program that creates 3 threads and prints alternate values in sequence.
