Java 番石榴| Floats.compare()方法与示例
原文:https://www . geesforgeks . org/Java-guava-floats-compare-method-with-examples/
Floats . compare()Floats 类的方法用于比较两个指定的Floats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(float a, float b)
参数:该方法接受两个参数:
- a: 是第一个要比较的浮动对象。
- b: 是第二个要比较的浮动对象。
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:该方法不抛出任何异常。
例 1:
// Java code to show implementation of
// Guava's Floats.compare() method
import com.google.common.primitives.Floats;
class GFG {
public static void main(String[] args)
{
float a = 4f;
float b = 4f;
// compare method in Float class
int output = Floats.compare(a, b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
Output:
Comparing 4.0 and 4.0 : 0
例 2:
// Java code to show implementation of
// Guava's Floats.compare() method
import com.google.common.primitives.Floats;
class GFG {
public static void main(String[] args)
{
float a = 4.2f;
float b = 3.1f;
// compare method in Float class
int output = Floats.compare(a, b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
Output:
Comparing 4.2 and 3.1 : 1
例 3:
// Java code to show implementation of
// Guava's Floats.compare() method
import com.google.common.primitives.Floats;
class GFG {
public static void main(String[] args)
{
float a = 2.5f;
float b = 4f;
// compare method in Float class
int output = Floats.compare(a, b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
Output:
Comparing 2.5 and 4.0 : -1
