What operations are defined for the strings in Java?concatenation with character strings and simple data types using Plussplitting of strings into parts of equal length by means of Split and a numberdeleting individual characters and components of a character string using minusduplication of strings by means of a mark

In Java, the following operations are defined for strings:

1. Concatenation: This operation is used to join two or more strings together. In Java, you can concatenate strings using the "+" operator. For example, "Hello" + " World" will result in "Hello World". You can also concatenate strings with other data types. For example, "The answer is: " + 42 will result in "The answer is: 42".

2. Splitting: The split() method in the String class is used to split a string into an array of substrings based on a specified delimiter. For example, "apple,banana,orange".split(",") will result in an array ["apple", "banana", "orange"].

3. Substring: The substring() method in the String class is used to get a part of the string. For example, "Hello World".substring(6) will result in "World".

4. Duplication: Strings in Java are immutable, which means once a String object is created, it cannot be changed. If you need to make a lot of modifications to Strings, you should use StringBuilder or StringBuffer which are mutable.

Note: There is no direct operation to delete individual characters from a string in Java. However, you can achieve this by creating a new string that does not include the character to be deleted.
