The most important point to understand is how Strings get created in java. When we create a String using string literal, it doesn’t change the value of original String. It creates a new String in the string pool and change the reference of the variable. So original string value is never...
Case mapping is based on the Unicode Standard version specified by the java.lang.Character Character class. The Java language provides special support for the string concatenation operator ( + ), and for conversion of other objects to strings. For additional information on string ...
