Fill elements in a Java float array in a specified range
Elements can be filled in a Java float array in a specified range using the java.util.Arrays.fill() method. This method assigns the required float value in the specified range to the float array in Java.
The parameters required for the Arrays.fill() method are the array name, the index of the first element to be filled(inclusive), the index of the last element to be filled(exclusive) and the value that is to be stored in the array elements.
A program that demonstrates this is given as follows −
Example
import java.util.Arrays;
public class Demo {
public static void main(String[] argv) throws Exception {
float[] floatArray = new float[10];
float floatValue = 5.8F;
int indexStart = 5;
int indexFinish = 9;
Arrays.fill(floatArray, indexStart, indexFinish, floatValue);
System.out.println("The float array content is: " + Arrays.toString(floatArray));
}
}Output
The float array content is: [0.0, 0.0, 0.0, 0.0, 0.0, 5.8, 5.8, 5.8, 5.8, 0.0]
Now let us understand the above program.
First, the float array floatArray[] is defined. Then the Arrays.fill() method is used to fill the float array with value 5.8 from index 5(inclusive) to index 9(exclusive). Finally, the float array is printed using the Arrays.toString() method. A code snippet which demonstrates this is as follows −
float[] floatArray = new float[10];
float floatValue = 5.8F;
int indexStart = 5;
int indexFinish = 9;
Arrays.fill(floatArray, indexStart, indexFinish, floatValue);
System.out.println("The float array content is: " + Arrays.toString(floatArray));
