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
