CaseFormat is a utility class for converting between various ASCII case formats. Behavior is undefined for non-ASCII input.
Declaration: The declaration for com.google.common.base.CaseFormat is as:
@GwtCompatible public enum CaseFormat extends Enum
Below table gives the summary of Enum Constants and their description:
Below table gives the summary of methods of CaseFormat class and their description:
Example 1:
// Java code to show implementation// of CaseFormat Class methods  import com.google.common.base.CaseFormat;  class GFG {      // Driver code    public static void main(String args[])    {          // A string variable named str        String str = "geeks_for_geeks";        System.out.println("Original String: "                           + str);          // "LOWER_UNDERSCORE" is a C++ variable        // naming convention        System.out.println("Lower Camel Format: "                           + CaseFormat                                 .LOWER_UNDERSCORE                                 .to(CaseFormat                                         .LOWER_CAMEL,                                     str));        // "UPPER_UNDERSCORE" is a Java and        // C++ constant naming convention        System.out.println("Upper Camel Format: "                           + CaseFormat                                 .UPPER_UNDERSCORE                                 .to(CaseFormat                                         .UPPER_CAMEL,                                     str));    }} |
Output:
Original String: geeks_for_geeks Lower Camel Format: geeksForGeeks Upper Camel Format: GeeksForGeeks
Example 2:
// Java code to show implementation// of CaseFormat Class methods  import com.google.common.base.CaseFormat;import java.util.*;  class GFG {      // Driver code    public static void main(String args[])    {          // Get the enum constants with the        // help of values() method        System.out.println("The Enum constants "                           + "of CaseFormat Class are:\n"                           + Arrays                                 .toString(CaseFormat                                               .values()));    }} |
Output:
The Enum constants of CaseFormat Class are:
[LOWER_HYPHEN, LOWER_UNDERSCORE, LOWER_CAMEL, UPPER_CAMEL, UPPER_UNDERSCORE]
