Java int array vs int array

Question

Is there a difference between  int   array   new int 10     and  int array     new int 10        Both do work  and the result is exactly the same  Which one is quicker or better  Is there a style guide which recommends one

User · Answer

Both are the same  I usually use int   array   new int 10    because of better  contiguous  readability of the type int

From JLS http   docs oracle com javase specs jls se5 0 html arrays html 10 2  Here are examples of declarations of array variables that do not create arrays   int    ai              array of int short       as             array of array of short Object      ao         array of Object         otherAo        array of Object Collection lt   gt     ca            array of Collection of unknown type short       s          scalar short          aas            array of array of short   Here are some examples of declarations of array variables that create array objects   Exception ae      new Exception 3    Object aao         new Exception 2  3   int    factorial     1  1  2  6  24  120  720  5040    char ac         n    o    t         a                          S    t    r    i    n    g      String    aas      array    of    String        The     may appear as part of the type at the beginning of the declaration  or as part of the declarator for a particular variable  or both  as in this example   byte    rowvector  colvector  matrix       This declaration is equivalent to   byte rowvector     colvector     matrix

There is virtually no difference

Both are equivalent  Take a look at the following   int   array      is equivalent to  int array        int var  array        is equivalent to  int var  int   array      int   array1  array2        is equivalent to  int   array1  int     array2      public static int   getArray                     is equivalent to  public static int getArray

There is no difference between these two declarations  and both have the same performance

User · Answer

No  there is no difference  But I prefer using int   array as it is more readable

User · Answer

They are both basically same  there is no difference in performance of any sort  the recommended one however is the first case as it is more readable   int   array   new int 10     FROM JLS      The    may appear as part of the type at the beginning of the   declaration  or as part of the declarator for a particular variable    or both

User · Answer

In both examples  you are assigning a new int 10  to a reference variable   Assigning to a reference variable either way will be equal in performance   int   array   new int 10     The notation above is considered best practice for readability   Cheers
