Cloning in Java allows you to create copies of objects, and the Cloneable interface and clone() method are the key components of this process. Deep cloning creates completely independent copies of objects and their internal objects, while shallow cloning results in copies that share references to some or all of the internal objects.

Serialization and deserialization are core concepts in Java that enable object persistence, data sharing, and network communication

Java loop constructs can be used to perform various tasks, such as iterating through arrays, processing collections, implementing algorithms, and more. When using loops, it’s important to consider loop termination conditions to avoid infinite loops, and to ensure the loop executes the desired number of times or until a specific condition is met.

if-else statements in Java programming allow developers to make decisions and control the flow of code based on specified conditions.

Method overriding is a powerful tool in the Java programming which enables customization, polymorphism, and code reuse. By allowing subclasses to redefine inherited methods, Java facilitates the creation of complex class into simple, understandable and respective behavioural functional class.

Method overloading is a form of polymorphism in Java, where a class can have multiple methods with the same name but different parameter lists.

To understand exceptional handling first it is required to understand the exception and why it should be handled in Java programs. Once we will understand this concept we can understand how to do exceptional handling. So we start with exception. What is Exception Exception means exceptional condition(s) or abnormal condition(s) which occurs during program execution….

If locale is specified in the method, it uses the specified locale otherwise uses the default locale calling from Locale.getDefault() during string conversion. Case mapping is based on…

Function Description Java String class lastIndexOf() method is used to get the index value of the last occurrence of the specified character within the string. It does backward search and backward search starts from the last index value or we can say at last character of the string. If fromIndex value is given, the backward…

Function Description Java String class indexOf() method is used to get the index value of the first occurrence of the specified character or the sequence of characters within the string. Search starts from the specified index, if fromIndex is given. If fromIndex value is not given, the search starts from 0 index. It returns -1,…

Function Description It is a native method. It is used to intern the string object that is created by a new keyword. After interning the string, it will be checked and created in the String constant pool. Once a String object is interned, it will check in String Constant Pool in place of heap memory….

Function Description This Java String Class method is used to break the string around all the matches of the specified regular expression and returns an Array. The array returned by this string contains each substring of the string that is broken by the sequence of characters matched to the specified regular expression. All broken substrings…

Function Description Java String class replaceAll() method is used to replace all occurrences of matching substring of the string with the given replacement string which matches the specified regular expression. Backslashes and dollar signs in the replacement are not being treated as a literal replacement string. To replace these special characters we need to use…

Function Description Java String class replace() method is used to replace all occurrences of the old character or sequence of characters respectively with new character or sequence of characters in the string. If the specified old character or sequence of characters is not found in the sting, It will return the same string. If the…

Function Description Java String Class replaceFirst() method is used to replace the first matching substring of the string with the specified replacement string which matches the given regular expression.
