Java Array setFloat() Method

The setFloat() method of Array class sets the value of the indexed component of the specified array object to the specified float value.

Syntax

public static void setFloat(Object array, int index, float f)
       throws IllegalArgumentException,
            ArrayIndexOutOfBoundsException

Parameter

array - the array

index - the index into the array

f - the new value of the indexed component

Returns

Does not return any value.

Throw

NullPointerException

IllegalArgumentException

ArrayIndexOutOfBoundsException -

NegativeArraySizeException

Example 1

//import statement

import java.lang.reflect.Array; 
public class ReflectArraysetFloatExample1 { 
    public static void main(String[] args) 
    { 
        float arr[] = new float[3];  
        Array.setFloat(arr , 0 , 2.4f);
          Array.setFloat(arr , 1 , 7.4f);
            Array.setFloat(arr , 2 , 9.4f);
        
        for (int i = 0; i < arr.length; i++) { 
  
            double vl = Array.getFloat(arr, i); 
            System.out.print(vl + "  , "); 
        } 
    }
