creating arrays in java

Creating arrays in java :
Arrays are objects in java ,and for that we create them using new operator .

For primitive data types :
java code

int[] myarr=new int[3];

For not primitive data types :

java code

car[] mycars=new car[3];

Once you specify the size of arrays , you can't change it later .

Assign values to arrays :
java code

myarr[0]=32;
        myarr[1]=12;
        myarr[2]=50;

for non primitive types :

java code

mycars[0]=new car("BMW");
        mycars[1]=new car("VOLVO");
        mycars[2]=new car("FIAT");

Create objects in the heap and assign it to the the array elements .

To copy one array to another one :
java code

String[] myStrings = {"one", "two", "three", "four", "five"};
        String[] copiedStrings = new String[4];
        // 1 is the start position in the orginal position
        // 0 is the start position in the copyTo position
        System.arraycopy(myStrings, 1, copiedStrings, 0, 4);
        for (int i = 0; i < copiedStrings.length; i++) {
            System.out.print(copiedStrings[i] + " , ");
        }

The output is :
java code

two , three , four , five ,
