爪哇番石榴| Longs.compare()方法与示例

原文:https://www . geesforgeks . org/Java-guava-longs-compare-method-with-examples/

Longs.compare() 法番石榴的 Longs 类用于比较两个指定的 long 值。这些值作为参数传递，比较的结果是第一个值和第二个值的差值。因此它可以是正的、零的或负的。

语法:

public static int compare(long a, long b)

参数:该方法接受两个参数:

  • a: 第一个比较的长物体。
  • b: 这是第二个要比较的长对象。

返回类型:这个方法返回一个 int 值。它返回:

  • 如果“a”等于“b”，则为 0，
  • 正值“a”大于“b”，
  • 负值“a”小于“b”

异常:该方法没有任何异常。

例 1:

// Java code to show implementation of
// Guava's Longs.compare() method
import com.google.common.primitives.Longs;

class GFG {
    public static void main(String[] args)
    {
        long a = 5L;
        long b = 5L;

        // compare method in Long class
        int output = Longs.compare(a, b);

        // printing the output
        System.out.println("Comparing " + a
                           + " and " + b + " : "
                           + output);
    }
}

Output:

Comparing 5 and 5 : 0

例 2:

// Java code to show implementation of
// Guava's Longs.compare() method
import com.google.common.primitives.Longs;

class GFG {
    public static void main(String[] args)
    {
        long a = 5L;
        long b = 4L;

        // compare method in Long class
        int output = Longs.compare(a, b);

        // printing the output
        System.out.println("Comparing " + a
                           + " and " + b + " : "
                           + output);
    }
}

Output:

Comparing 5 and 4 : 1

例 3:

// Java code to show implementation of
// Guava's Longs.compare() method
import com.google.common.primitives.Longs;

class GFG {
    public static void main(String[] args)
    {
        long a = 4L;
        long b = 5L;

        // compare method in Long class
        int output = Longs.compare(a, b);

        // printing the output
        System.out.println("Comparing " + a
                           + " and " + b + " : "
                           + output);
    }
}

Output:

Comparing 4 and 5 : -1
