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
