Java double Array

It is used to store double data type values only. With the following examples you can learn how to declare double array, how to assign values to double array and how to get values from double array.

Java double Array Example
/* double Array Example */
/* Save with file name DoubleArray.java */

public class DoubleArray
{
	public static void main(String args[])
	{
		//DOUBLE ARRAY DECLARATION
		double a[];
		//MEMORY ALLOCATION FOR DOUBLE ARRAY
		a = new double[4];
		//ASSIGNING ELEMENTS TO DOUBLE ARRAY
		a[0] = 100000d;
		a[1] = 300000d;
		a[2] = 400000d;
		a[3] = 786777d;
		//DOUBLE ARRAY OUTPUT
		System.out.println();
		System.out.println("double Array Example");
		System.out.println("==================");
		System.out.println();
		for(int i=0;i<a.length;i++)
		{
			System.out.println("Element at Index : "+ i + " " + a[i]);
		}
	}
}
                        

In this example you can learn how to assign values to double array at the time of declaration.

Java double Array Example 2
/* double Array Example 2 */
/* Save with file name DoubleArray2.java */

public class DoubleArray2
{
	public static void main(String args[])
	{
		//DOUBLE ARRAY DECLARATION
		double a[] = {100000d,300000d,400000d,786777d};
		//DOUBLE ARRAY OUTPUT
		System.out.println();
		System.out.println("double Array Example");
		System.out.println("==================");
		System.out.println();
		for(int i=0;i<a.length;i++)
		{
			System.out.println("Element at Index : "+ i + " " + a[i]);
		}
	}
}
                        

In this example you can learn how to declare double array with other double variables.

Java double Array Example 3
/* double Array Example 3 */
/* Save with file name DoubleArray3.java */

public class DoubleArray3
{
	public static void main(String args[])
	{
		//DOUBLE ARRAY DECLARATION
		double a[], a2;
		//MEMORY ALLOCATION FOR DOUBLE ARRAY
		a = new double[4];
		//ASSIGNING ELEMENTS TO DOUBLE ARRAY
		a[0] = 100000d;
		a[1] = 300000d;
		a[2] = 400000d;
		a[3] = 786777d;
		a2 = 333333d;
		//DOUBLE ARRAY OUTPUT
		System.out.println();
		System.out.println("double Array Example");
		System.out.println("==================");
		System.out.println();
		System.out.println("a2 value is : "+a2);
		System.out.println();
		for(int i=0;i<a.length;i++)
		{
			System.out.println("Element at Index : "+ i + " " + a[i]);
		}
	}
}
                        

In this example you can learn how to assign double array to other double array.

Java double Array Example 4
/* double Array Example 4 */
/* Save with file name DoubleArray4.java */

public class DoubleArray4
{
	public static void main(String args[])
	{
		//DOUBLE ARRAY DECLARATION
		double[] a, a2; //a AND a2 ARE ARRAY VARIABLES
		//MEMORY ALLOCATION FOR DOUBLE ARRAY
		a = new double[4];
		//ASSIGNING ELEMENTS TO DOUBLE ARRAY
		a[0] = 100000d;
		a[1] = 300000d;
		a[2] = 400000d;
		a[3] = 786777d;
		//ASSIGNING a ARRAY TO a2 ARRAY VARIABLE
		a2 = a;
		//DOUBLE ARRAY OUTPUT
		System.out.println();
		System.out.println("double Array Example");
		System.out.println("==================");
		System.out.println();
		System.out.println("a array values");
		System.out.println();
		for(int i=0;i<a.length;i++)
		{
			System.out.println("Element at Index : "+ i + " " + a[i]);
		}
		System.out.println();
		System.out.println("a2 array values");
		for(int i=0;i<a2.length;i++)
		{
			System.out.println("Element at Index : "+ i + " " + a2[i]);
		}
	}
}
