Yes, we can write a method using variable arguments once you use variable arguments as a parameter method while calling you can pass as many numbers of arguments to this method (variable number of arguments) or, you can simply call this method without passing any arguments.ExampleLive Demopublic class Sample{    void demoMethod(String... args) {       for (String arg : args) {          System.out.println(arg);       }    }    public static void main(String args[] ){       new Sample().demoMethod("ram", "rahim", "robert");       new Sample().demoMethod("krishna", "kasyap");       new Sample().demoMethod();    } }Outputram rahim robert krishna kasyap

It is a common and routine task in Python; the act of writing binary data to a file when you need to save non-textual data such as images, audio files, or serialized objects. In this article, we will explore various ways how you can write binary data to a file using Python and provide you with code examples followed by comprehensive explanations to help you grasp the concept. To write binary data to a file in Python, you can follow these steps: Open the File in Binary Mode First, you should proceed to open the file in ... Read More

If a function is inline, the compiler places a copy of the code of that function at each point where the function is called at compile time. Any change to an inline function could require all clients of the function to be recompiled because compiler would need to replace all the code once again otherwise it will continue with old functionality. No, Java does not provide inline functions it is typically done by the JVM at execution time.

Following are the notable differences between non-static methods and abstract methods.Non-static (normal) methodsAbstract methodsThese methods contain a body.Abstract methods don’t have body these are ended with a semicolonYou can use normal method directly.You cannot use abstract methods directly, to use them you need to inherit them and provide body to these methods and use them.Example:public void display() {    System.out.println("Hi"); }Example:public void display();

The creation and modification datetime of a file in Python are defined as the timestamps associated with the events of when the file was created and when it was last modified. Creation datetime: It is defined as the timestamp when a file was initially created or added to the file system. Modification datetime: It is defined as the timestamp when the file's content was last modified or updated. These datetimes can provide a lot of information such as the file's age, recent changes, or when it was first introduced. In Python, you can fetch the ... Read More

For this purpose, we create an object of HashMap class which is defined in java.util packageMap map = new HashMap();This hashmap object associates each digit with its corresponding word representationmap.put("0", "zero");Initialize an empty string object.String newstr="";Next, run a for loop over the length of given string and extract each character by substring() method of String class.Check if the character exists as a key in map object by containsKey() method. If it does, using it as key, obtain its value component in map and appenf\d to the new string. If not append the character itself to the new string. The complete code ... Read More

While choosing an identifier to declare a variable in Java you need to keep the following points in mind. The name of the variable should begin with either alphabet or, an underscore (_) or, a dollar ($) sign. The identifiers used for variables must not be keywords. No spaces or special characters are allowed in the variable names of Java. Variable names may contain 0 to 9 numbers (if not at the beginning). Variable names are case sensitive i.e. MY_NUM is different from my_num. If you use two words in a identifier then the you should follow camel case ... Read More

There will be times when we need to remove files programmatically in Python. Removing files, in this context, is the act of deleting or erasing files from a computer's file system using Python programming language. You must know that when you remove a file, it is permanently deleted from the storage location; this frees up disk space and makes the file inaccessible. Python has a number of modules and functions, such as os.remove() or os.unlink(), that permit you to interact with the operating system and remove files using code. This functionality is particularly useful when we want to automate tasks, ... Read More

While writing a method name we should follow the camel case i.e. first letter of the first word should be small and the first letters of the remaining (later) words should be capital. Example public class Test { public void sampleMethod() { System.out.println("This is sample method"); } public void demoMethod() { System.out.println("This is demo method"); } public static void main(String args[]) { Test obj = new Test(); obj.sample(); obj.demo(); } } Output This is sample method This is demo method

While writing class names you need to keep the following points in mind. You shouldn’t use predefined or existing class names as the name of the current class. You shouldn’t use any Java keywords as class name (with the same case). The First letter of the class name should be capital and remaining letters should be small (mixed case). class Sample Likewise, first letter of each word in the name should be capital an remaining letters should be small. class Test Keeping interface names simple and descriptive is suggestable. Better not ... Read More
