array in java

int intArray[];    //declaring array
intArray = new int[20];  // allocating memory to array
//OR
int[] intArray = new int[20]; // combining both statements in oneString[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
cars[0] = "Opel";
System.out.println(cars[0]);
// Now outputs Opel instead of Volvo
//method 1
int[] age = new int[3];
        age[0] = 1;
        age[1] = 3;
        age[2] = 6;

        for (int i=0; i < 3; i++)
            System.out.println(age[i]);

//method 2
        int[] num = {3,3,5};
        //int num[] = {3,3,5}; also works the same

        System.out.println(num[0]);//Metodo 1
type nome = new type[n];

//Metodo 2
type nome[];
nome = new type[n]; int[] intArray = new int[]{ 1,2,3,4,5,6,7,8,9,10 }; 
 // Declaring array literaltype nome[] = new type[n];
