String array initialization in Java

Question

If I declare a String array   String names     new String 3     Then why can t we assign values to the array declared above like this   names     Ankit   Bohra   Xyz

User · Answer

You can do the following during declaration:

String names[] = {"Ankit","Bohra","Xyz"};

And if you want to do this somewhere after declaration:

String names[];
names = new String[] {"Ankit","Bohra","Xyz"};

First up  this has got nothing to do with String  it is about arrays   and that too specifically about declarative initialization of arrays   As discussed by everyone in almost every answer here  you can  while declaring a variable  use   String names       x   y   z      However  post declaration  if you want to assign an instance of an Array   names   new String     a   b   c      AFAIK  the declaration syntax is just a syntactic sugar and it is not applicable anymore when assigning values to variables because when values are assigned you need to create an instance properly   However  if you ask us why it is so  Well    good luck getting an answer to that  Unless someone from the Java committee answers that or there is explicit documentation citing the said syntactic sugar

You mean like   String names       Ankit   Bohra   Xyz      But you can only do this in the same statement when you declare it

It is just not a valid Java syntax  You can do  names   new String     Ankit   Bohra   Xyz

User · Answer

names       Ankit   Bohra   Xyz      is an initializer and used solely when constructing or creating a new array object  It cannot be used to set the array  You can use it when declared as   String   names    Ankit   Bohra   Xyz      You may also use   names new String     Ankit   Bohra   Xyz
