Java short Array
short Array in Java
Java short array is used to store short data type values only. The default value of the elements in a short array is 0.
With the following Java short array examples you can learn
- how to declare Java short array
- how to assign values to Java short array
- how to get values from Java short array
Initializing a short Array in Java
Arrays are declared with [] (square brackets). If you put [] (square brackets) after any variable of any type only that variable is of type array remaining variables in that declaration are not array variables those are normal variables of that type.
If you put [] (square brackets) after any data type all the variables in that declaration are array variables. All the elements in the array are accessed with index. The array element index is starting from 0 to n-1 number i.e. if the array has 5 elements then starting index is 0 and ending index is 4.
// declares an array of shorts
short[] shortArray;
What is the Length of an Array in Java ?
In Java all the arrays are indexed and declared by int only. That is the size of an array must be specified by an int value and not long or short. All the arrays index beginning from 0 to ends at 2147483646. You can store elements upto 2147483647. If you try to store long (big) elements in array, you will get performance problems. If you overcome performance problems you should go to java collection framework or simply use Vector.
Syntax :
< data type > < variable >[];
< data type >[] < variable >;
Java short Array Example
/* Java short Array Example
Save with file name ShortArray.java */
public class ShortArray
{
public static void main(String args[])
{
//JAVA SHORT ARRAY DECLARATION
short s[];
//MEMORY ALLOCATION FOR JAVA SHORT ARRAY
s = new short[4];
//ASSIGNING ELEMENTS TO JAVA SHORT ARRAY
s[0] = 10;
s[1] = 30;
s[2] = 40;
s[3] = 7;
//JAVA SHORT ARRAY OUTPUT
System.out.println("Java short Array Example");
for(int i=0;i<s.length;i++)
{
System.out.println("Element at Index : "+ i + " " + s[i]);
}
}
}
Following Java short array example you can learn how to assign values to Java short array at the time of Java short array declaration.
How to assign values to Java short array at the time of Java short array declaration
/* How to assign values to Java short array at the time of Java short array declaration Example
Save with file name ShortArray2.java */
public class ShortArray2
{
public static void main(String args[])
{
//JAVA SHORT ARRAY DECLARATION AND ASSIGNMENT
short s[] = {10,30,40,7};
//JAVA SHORT ARRAY OUTPUT
System.out.println("Java short Array Example");
for(int i=0;i<s.length;i++)
{
System.out.println("Element at Index : "+ i + " " + s[i]);
}
}
}
Following Java short array example you can learn how to declare Java short array with other Java short array variables.

public class ShortArray3
{
public static void main(String args[])
{
//JAVA SHORT ARRAY DECLARATION
short s[], s2; //s IS AN ARRAY s2 IS NOT AN ARRAY
//MEMORY ALLOCATION FOR JAVA SHORT ARRAY

//ASSIGNING ELEMENTS TO JAVA SHORT ARRAY
s[0] = 10;
s[1] = 30;
s[2] = 40;
s[3] = 7;
s2 = 101;
//JAVA SHORT ARRAY OUTPUT
System.out.println("Java short Array Example");
System.out.println("value of s2 : "+s2);
for(int i=0;i<s.length;i++)
{
System.out.println("Element at Index : "+ i + " " + s[i]);
}
}
}
Following Java short array example you can learn how to assign Java short array to other Java short array.
