下表给出了 CaseFormat 类的方法概要及其描述:
例 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
例 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:
CaseFormat 类的枚举常量有: 【下连字符，下下划线，下骆驼，上骆驼，上下划线】
