Unless otherwise noted, methods for comparing Strings do not take locale into account. The Collator class provides methods for finer-grain, locale-sensitive String comparison.Implementation Note: The implementation of the string concatenation operator is left to the discretion of a Java compiler, as ...
The class String includes methods for examining individual characters of the sequence, for comparing strings, for searching strings, for extracting substrings, and for creating a copy of a string with all characters translated to uppercase or to lowercase. Case mapping is based on the Unicode Stan...
Strings in Java are a widely used data type (and in most programming languages), they allow us to store anything and everything that has to do with words, sentences, phone numbers, or even just regular numbers. But, as useful as they are, you'll need to know a few important things a...

In the following Java program, we have created twoStringobjects. First we are comparing the objects using the equals operator which results infalsebecause both are different objects in memory. Then we check the content of strings using theequals()that returnstruebecause even though objects are dif...

In Java 1.1 and later, the java.text package provides a sophisticated set of classes for comparing strings, even in different languages. German, for example, has vowels with umlauts over them and a beta-like character that represents a double “s”. How should we sort these? Although the ...
