Floats类的Floats.compare()方法用于比较两个指定的float值。这些值作为参数传递,比较结果作为第一值和第二值之差得到。因此,它可以为正,零或负。
用法:
public static int compare(float a, float b)
参数:此方法接受两个参数:
- a:这是要比较的第一个float对象。
- b:这是要比较的第二个float对象。
返回类型:此方法返回一个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:该方法不会引发任何异常。
范例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);
}
}
输出:
Comparing 4.0 and 4.0:0
范例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);
}
}
输出:
Comparing 4.2 and 3.1:1
范例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);
}
}
输出:
Comparing 2.5 and 4.0:-1
