Java番石榴 |带有示例的 Chars.compare() 方法
Guava 的 Chars 类的Chars.compare()方法用于比较两个指定的char值。这些值作为参数传递,比较结果作为第一个值和第二个值的差值。因此,它可以是正数、零或负数。
句法:
public static int compare(char a, char b)
参数:此方法接受两个参数:
- a:这是要比较的第一个 char 对象。
- b:这是要比较的第二个 char 对象。
返回类型:此方法返回一个 int 值。它返回:
- 0 如果“a”等于“b”,
- 正值“a”大于“b”,
- 负值“a”小于“b”
异常:该方法没有任何异常。
示例 1:
// Java code to show implementation of
// Guava's Chars.compare() method
import com.google.common.primitives.Chars;
class GFG {
public static void main(String[] args)
{
char a = 'c';
char b = 'c';
// compare method in Char class
int output = Chars.compare(a, b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
输出:
Comparing c and c : 0
示例 2:
// Java code to show implementation of
// Guava's Chars.compare() method
import com.google.common.primitives.Chars;
class GFG {
public static void main(String[] args)
{
char a = 'd';
char b = 'D';
// compare method in Char class
int output = Chars.compare(a, b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
输出:
Comparing d and D : 32
示例 3:
// Java code to show implementation of
// Guava's Chars.compare() method
import com.google.common.primitives.Chars;
class GFG {
public static void main(String[] args)
{
char a = 'E';
char b = 'c';
// compare method in Char class
int output = Chars.compare(a, b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
输出:
Comparing E and c : -30
