Convert a Float Array to String in Java

Declaration :

public static String toString(float[] a)

1	public static String toString(float[] a)

Explanation :

Purpose	The java.util.Arrays.toString(float[]) method returns a string representation of the contents of the specified float array. The string representation consists of a list of the array’s elements enclosed in square brackets (“[]”). Adjacent elements are separated by the characters ” ” (a comma followed by a space).
Parameters	a ===> This is the array whose string representation to return.
Return Value	This method returns a string representation of a.
Exception	NA

Java Program : Example

Below example will explain java.util.Arrays.toString() method.

package com.c4learn;
import java.util.Arrays;
public class ArrayDemo {
	public static void main(String[] args) {
		// Initialize the float array
		float[] arrF = new float[] { 10.2f, 20.2f, 30.2f };
		// Print the float array
		System.out.println("The array is:");
		for (float num : arrF) {
			System.out.println("Element Value is " + num);
		}
		System.out.println("\nString Representation :");
		System.out.println(Arrays.toString(arrF));
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize the float array

float[] arrF = new float[] { 10.2f, 20.2f, 30.2f };

// Print the float array

System.out.println("The array is:");

for (float num : arrF) {

System.out.println("Element Value is " + num);

}

System.out.println("\nString Representation :");

System.out.println(Arrays.toString(arrF));

}

Output of Program :

The array is:
Element Value is 10.2
Element Value is 20.2
Element Value is 30.2
String Representation :
[10.2, 20.2, 30.2]

The array is:

Element Value is 10.2

Element Value is 20.2

Element Value is 30.2

String Representation :

[10.2, 20.2, 30.2]
