Java substring how to#

In this Java Tutorial, we have learnt the syntax of Java StringBuilder.substring() function, and also learnt how to use this function with the help of examples. ('Sub String : '+ stringBuilder.substring(8, 2)) Д®xception in thread 'main' : start 8, end 2, length 12ДЄt java.base/(Unknown Source)ДЄt java.base/(Unknown Source)ДЄt java.base/(Unknown Source)ДЄt Example.main(Example.java:12) Conclusion We will give a value for start parameter such that it is greater than end. In this example, we will test a negative scenario where substring() throws. Sub String : fgh Example 4 вЂ“ substring(int start, int end) ('Sub String : '+ stringBuilder.substring(5, 8)) get substring start from index 5 to index 8 Here, the parameter beginIndex is inclusive. substring(int beginIndex) substring(int beginIndex, int endIndex) substring(int beginIndex) returns the substring of this string which will start from the character at the beginIndex and will extend to the end of the string. StringBuilder stringBuilder = new StringBuilder('abcdefghijklmn') In Java substring() method has two variants. We will then get the sub-string from the StringBuilder using substring() method from starting position of 5 and ending position of 8 in the character sequence of StringBuilder Example 3 вЂ“ substring(int start, int end) Integer representing the end position of substring in StringBuilder. The syntax of substring() function is substring(int start, int end) StringBuilder.substring() returns a new String that contains a subsequence of characters currently contained in this sequence, whose starting and ending are provided as arguments. Output Exception: : start -7, end 13, length 13 substring(int start, int end) StringBuilder str = new StringBuilder('abcdefghijklm') We will give an index that is out of range for the sequence in StringBuilder. Thus the length of the substring is endIndex-beginIndex. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. It returns a new string that is a substring of this string. In this example, we will test a negative scenario where substring() throws . The substring (int beginIndex, int endIndex) method of the String class. Sub String : fghijkl Example 2 вЂ“ substring(int start) ('Sub String : '+ stringBuilder.substring(5)) StringBuilder stringBuilder = new StringBuilder('abcdefghijkl') We will then get the sub-string from the StringBuilder using substring() method from starting position of 5 in the character sequence of StringBuilder. In this example, we will create a StringBuilder object and initialize with some string passed as argument. Integer representing the start position of substring in StringBuilder. The syntax of substring() function is substring(int start)

StringBuilder.substring() returns a new String that contains a subsequence of characters, formed using start position and an optional end position, contained in this character sequence.
