Floats is a utility class for primitive type float. It provides Static utility methods pertaining to float primitives, that are not already found in either Float or Arrays.
Declaration :
@GwtCompatible(emulated=true) public final class Floats extends Object
Below table shows the Field summary for Guava Floats Class :
Some of the methods provided by Guava Floats Class are :
Exceptions :
- min : IllegalArgumentException if array is empty.
- max : IllegalArgumentException if array is empty.
- ensureCapacity : IllegalArgumentException if minLength or padding is negative.
- toArray : NullPointerException if collection or any of its elements is null.
Below table shows some other methods provided by Guava Floats Class :
Below given are some examples showing the implementation of methods of Guava Floats Class :
Example 1 :
// Java code to show implementation // of Guava Floats.asList() method import com.google.common.primitives.Floats;
import java.util.*;
class GFG {
// Driver method
public static void main(String[] args)
{
float arr[] = { 2 .6f, 4 .6f, 1 .2f, 2 .4f, 1 .5f };
// Using Floats.asList() method which
// converts array of primitives to array of objects
List<Float> myList = Floats.asList(arr);
// Displaying the elements
System.out.println(myList);
}
} |
Output :
[2.6, 4.6, 1.2, 2.4, 1.5]
Example 2 :
// Java code to show implementation // of Guava Floats.toArray() method import com.google.common.primitives.Floats;
import java.util.*;
class GFG {
// Driver method
public static void main(String[] args)
{
List<Float> myList = Arrays.asList( 2 .6f, 4 .6f, 1 .2f, 2 .4f, 1 .5f);
// Using Floats.toArray() method which
// converts a List of Floats to an
// array of float
float [] arr = Floats.toArray(myList);
// Displaying the elements
System.out.println(Arrays.toString(arr));
}
} |
Output :
[2.6, 4.6, 1.2, 2.4, 1.5]
Example 3 :
// Java code to show implementation // of Guava Floats.concat() method import com.google.common.primitives.Floats;
import java.util.*;
class GFG {
// Driver method
public static void main(String[] args)
{
float [] arr1 = { 2 .6f, 4 .6f, 1 .2f };
float [] arr2 = { 2 .4f, 1 .5f };
// Using Floats.concat() method which
// combines arrays from specified
// arrays into a single array
float [] arr = Floats.concat(arr1, arr2);
// Displaying the elements
System.out.println(Arrays.toString(arr));
}
} |
Output :
[2.6, 4.6, 1.2, 2.4, 1.5]
Example 4 :
// Java code to show implementation // of Guava Floats.contains() method import com.google.common.primitives.Floats;
class GFG {
// Driver method
public static void main(String[] args)
{
float [] arr = { 2 .6f, 4 .6f, 1 .2f, 2 .4f, 1 .5f };
// Using Floats.contains() method which
// checks if element is present in array
// or not
System.out.println(Floats.contains(arr, 2 .5f));
System.out.println(Floats.contains(arr, 1 .5f));
}
} |
output :
false true
Example 5 :
// Java code to show implementation // of Guava Floats.min() method import com.google.common.primitives.Floats;
class GFG {
// Driver method
public static void main(String[] args)
{
float [] arr = { 2 .6f, 4 .6f, 1 .2f, 2 .4f, 1 .5f };
// Using Floats.min() method
System.out.println(Floats.min(arr));
}
} |
Output :
1.2
Example 6 :
// Java code to show implementation // of Guava Floats.max() method import com.google.common.primitives.Floats;
class GFG {
// Driver method
public static void main(String[] args)
{
float [] arr = { 2 .6f, 4 .6f, 1 .2f, 2 .4f, 1 .5f };
// Using Floats.max() method
System.out.println(Floats.max(arr));
}
} |
Output :
4.6
