Java番石榴 |带有示例的 Longs.compare() 方法
Guava 的 Longs 类的Longs.compare()方法用于比较两个指定的long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(long a, long b)
参数:此方法接受两个参数:
- a:这是要比较的第一个长对象。
- b:这是要比较的第二个长对象。
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 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);
}
}
输出:
Comparing 5 and 5 : 0
示例 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);
}
}
输出:
Comparing 5 and 4 : 1
示例 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);
}
}
输出:
Comparing 4 and 5 : -1
