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 long as the compiler ultimately conforms to The Java™ Language Specification. For ...
If they have different characters at one or more index positions, let k be the smallest such index; then the string whose character at position k has the smaller value, as determined by using the < operator, lexicographically precedes the other string. In this case, compareTo returns the ...
