Java-Shortcut method for Array Declaration,Creation,Initialization into a single line

1.For 1-D Array:-
We can declare ,create & initialize an array into a single line.
This is the short cut method what we are discussing here.
let's go...

example :
                  int [ ] x= new  int [3];
                        x[0]=10;
                        x[1]=20;
                        x[2]=30;

we can do this into a single line as follows:-

             int [ ] x={10,20,30};          (perfectly valid)


But if we want to use this shortcut compulsory we should perform all activities into a single line only.
if we are trying to do in multiple lines then we will get Compile-Time Error.

example:-
                int [ ] x ;                   Declaration is valid
                x={10,20,30}          But  Compile-Time Error : Illegal start of Expression




2.For 2-D Array:-
 we can use this shortcut method even for multidimensional array also.

             int [ ] [ ] x={{10,20},{30,40,50}};             (perfectly valid)

 3. For 3-D Array
 example:

         int [ ] [ ] [ ]   x = int {{{10,20,30},{40,50,60}},{{70,80},{90,100,110}}};

Try to find out the outputs:-
 System.out.println(x[0][1][2]);
 System.out.println(x[1][0][1]);
 System.out.println(x[2][0][0]);
 System.out.println(x[1][2][0]);
 System.out.println(x[1][1][1]);



Now scroll down for answers:





 System.out.println(x[0][1][2]);           o/p is           60
 System.out.println(x[1][0][1]);           o/p is           80
 System.out.println(x[2][0][0]);         Runtime Exception :ArrayIndesxBoundException
 System.out.println(x[1][2][0]);         Runtime Exception :ArrayIndesxBoundException
 System.out.println(x[1][1][1]);          o/p is           100
