The Collator class provides methods forДЇiner-grain, locale-sensitive String comparison.

Unless otherwise noted, methods for comparing Strings do not take locale

The Java language provides special support for the stringД¬oncatenation operator (В +В ), and for conversion of Case mapping is based on the Unicode Standard version Searching strings, for extracting substrings, and for creating aД¬opy of a string with all characters translated to uppercase or to Individual characters of the sequence, for comparing strings, for The class String includes methods for examining Here are some more examples of how strings can be used: String buffers support mutable strings.Д«ecause String objects are immutable they can be shared. Strings are constant their values cannot be changed after theyДЄre created. String literals in Java programs, such as 'abc', are

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.The String class represents character strings. ('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 StringBuilder stringBuilder = new StringBuilder('abcdefghijklmn') 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. 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.
