Java array of array of objects

Question

This is what I need in pseudocode:

myArray = {
 {Object, Object, Object},
 {Object, Object, Object},
 {Object, Object, Object},
 {Object, Object, Object},
 {Object, Object, Object},
}

How can I declare and initialize something like this in real Java?

• JB Nizet: The use of 2-dimensional array is often a symptom of a lack of object design and encapsulation. You should probably use a one-dimensional array (or List, or Set) of Triple instances. A Triple being an object encapsulating your three other objects, and providing useful, high-level methods.

Answer 1

Just like this...

Object[][] myArray = {
 {obj11, obj12, obj13},
 {obj21, obj22, obj23},
 {obj31, obj32, obj33},
 {obj41, obj42, obj43},
 {obj51, obj52, obj53},
};

Also, see Oracle's array tutorial.

• Ted Hopp: +1 If myArray is declared separately, you need to change this a little bit to: myArray = new Object[][] { ... };
