Declaring, creating, and assigning the array elements in a single line. 

Syntax:

datatype arrayName[] = { list of values }; 

Within the {} we can specify any number of values separated by a comma. 

• When we are declaring, creating and assigning the values in a single line, then we need not specify the size of the array. 
• The creation of array will be done by JVM and the size of the array is also decided by JVM based on number of values specified within the {}. 
• Once the size of the array is decided the JVM itself will assign the values to the array element 

Example: int [] arr = {10,20,30,40,50}

Program

class ArrayDemo { 

  public static void main (String[] args) { 

     int[] iarr = {12,34,45,67,89}; 

     for(int x iarr) { 

         System.out.println(x); 

     } 

     double []darr = {1.1,2.2, 3.3,4.4,5.5,6.6}; 

     for(double y: darr) { 

     System.out.println(y); 

     } 

     char carr[] = ('a','b','c','d'); 

     for(char z:carr) { 

        System.out.println(z) 

        } 

   } 

}
