Initializing multiple variables to the same value in Java

Question

I m looking for a clean and efficient method of declaring multiple variables of the same type and of the same value  Right now I have   String one       two       three      etc      But I m looking for something like   String one two three        Is this something that is possible to do in java  Keeping efficiency in mind

No  it s not possible in java   You can do this way    But try to avoid it   String one  two  three  one   two   three

String one  two  three  one   two   three         This should work with immutable objects  It doesn t make any sense for mutable objects for example   Person firstPerson  secondPerson  thirdPerson  firstPerson   secondPerson   thirdPerson   new Person      All the variables would be pointing to the same instance  Probably what you would need in that case is   Person firstPerson   new Person    Person secondPerson   new Person    Person thirdPerson   new Person      Or better yet use an array or a Collection

You can declare multiple variables  and initialize multiple variables  but not both at the same time    String one two three   one   two   three         However  this kind of thing  especially the multiple assignments  would be frowned upon by most Java developers  who would consider it the opposite of  visually simple

Way too late to this but the simplest way I ve found is  String foo   bar   baz    quot hello quot  println foo  println bar  println baz   Output  hello hello hello

I do not think that is possible you have to set all the values individualling  like the first example you provided    The Second example you gave  will only Initialize the last varuable to    and not the others

Works for primitives and immutable classes like String  Wrapper classes Character  Byte    int i 0 j 2    String s1 s2   s1   s2    java rocks    For mutable classes   Reference r1   Reference r2   Reference r3   new Object         Three references   one object are created  All references point to the same object and your program will misbehave

You can do this   String one  two  three   two   one         But these will all point to the same instance  It won t cause problems with final variables or primitive types  This way  you can do everything in one line
