Java Guava Chars.compare()用法及代碼示例


Guava的Chars類的Chars.compare()方法用於比較兩個指定的char值。這些值作為參數傳遞,比較結果作為第一值和第二值之差得到。因此,它可以為正,零或負。

用法:

public static int compare(char a, char b)

參數:此方法接受兩個參數:


  • a:這是第一個要比較的char對象。
  • b:這是要比較的第二個char對象。

返回類型:此方法返回一個int值。它返回:

  • 如果“ a”等於“ b”,則為0,
  • 正值“ a”大於“ b”,
  • 負值“ a”小於“ b”

異常:該方法沒有任何異常。

範例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); 
    } 
}
輸出:
Comparing c and c:0

範例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); 
    } 
}
輸出:
Comparing d and D:32

範例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); 
    } 
}
輸出:
Comparing E and c:-30
