Java 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]);
		}
	}
}
