The Java String subSequence function is used to extract a portion of a string and return it as a new string. It takes two parameters: the starting index and the ending index (exclusive) of the substring to be extracted. The function returns a CharSequence object, which can be cast to a String if needed. The subSequence function does not modify the original string, but instead creates a new string that contains the specified portion of the original string. This function is useful when you need to work with a specific part of a larger string, such as extracting a username from an email address.

Java String subSequence in C# With Example Code
Java String subSequence method is used to extract a part of the string. It returns a new character sequence that is a subsequence of this sequence. The subsequence starts with the character at the specified index and extends to the end of this sequence or up to endIndex – 1 if the second argument is given.
In C#, we can achieve the same functionality using the Substring method. The Substring method is used to extract a substring from a string. It takes two arguments, the starting index and the length of the substring.
Here is an example code snippet that demonstrates how to use the Substring method to achieve the same functionality as the Java String subSequence method:
string str = "Hello World";
string subStr = str.Substring(6, 5);
Console.WriteLine(subStr); // Output: World
In the above example, we have a string “Hello World”. We are using the Substring method to extract a subsequence starting from index 6 and having a length of 5. The resulting substring is “World”.
In conclusion, the Java String subSequence method can be easily achieved in C# using the Substring method.
Equivalent of Java String subSequence in C#
In conclusion, the equivalent function to Java’s String subSequence in C# is the Substring method. Both functions serve the same purpose of extracting a portion of a string based on a specified start and end index. However, there are some differences in the syntax and usage of these functions. While Java’s subSequence method returns a CharSequence object, C#’s Substring method returns a string object. Additionally, the parameters for the start and end index in C# are inclusive, whereas in Java, the end index is exclusive. Despite these differences, both functions are useful tools for manipulating strings in their respective programming languages.
