Introduction to Java Parse String
Parsing String in java is known as converting data in the String format from a file, user input, or a certain network. Parsing String is the process of getting information that is needed in the String format. String parsing in java can be done by using a wrapper class. Using the Split method, a String can be converted to an array by passing the delimiter to the split method. The split method is one of the methods of the wrapper class.
String parsing can also be done through StringTokenizer. StringTokenizer class allows its constructor to break the String into tokens. StringTokenizer is much simpler than other classes. StringTokenizer is a legacy class, so everyone must avoid the use of this class.
Web development, programming languages, Software testing & others
Syntax:
In the above syntax, multiple delimiter can be used inside the square brackets. “+” sign after bracket treats multiple delimiter as a single delimiter.
Initialization of Parse String
In java, a String can be converted into char, Object, int, date, time, etc. String parsing is initialized by a certain java class method as per the data type is required.
Example #1
In this example, we can see how String is parsing into different types of formats like date & integer. Similarly, we can use other methods to convert a string into other formats.
Code:
Output:
Output for the above-given program is given below; we can see how String is converted into different data type by using different methods.
Example #2
In this example, using the split method for parsing of the string to array format.
Code:
Output:
The above given an example contains three sections, all the three-section using the different delimiter for parsing the String. In the below-given screenshot, we can see the output of the above-given program.
Example #3
In this example, the StringTokenizer class is used for parsing. The StringTokenizer class’s constructor takes two parameters: the first one is the string & the second one is the delimiter. This class contains some methods, i.e. hasMoreElements() to check whether the next index holding any value or not while nextElement() returns the value at the next index.
Code:
Output:
The above parsing output is given below; we can see how comma-separated values are listed in the next column. 
Example #4
This example shows how the indexOf method can be used effectively to parse any String in java. In this program, a String in the middle of the sentence is being converted to uppercase.
Code:
Output: Output of the above-given program is given below.
Example #5
In this example, we can see how a string is converted into an array of chars.
Code:
Output:
The Output for the above-given program is given below.
In the attached output screenshot, we can see how a String is converted into the array of characters by using methods toCharArray().
Conclusion – Java Parse String
In the above-given Article, we have gone through the parsing, String parsing in Java, etc. How the split method plays a role in parsing the data type. Some other ways are also available which can be used for parsing, such as StringTokenizer.
