TypeConversionDemo.java

public class TypeConversionDemo
{

    public static void main(String[] args)
    {
        double doubleVariable;
        long longVariable;
        int intVariable = 10;

        /*
         * Variable of smaller capacity is be assigned to another variable of
         * bigger capacity.
         */
        longVariable = intVariable;
        doubleVariable = intVariable;

        System.out.println("longVariable : " + longVariable);
        System.out.println("doubleVariable : " + doubleVariable);

    }

}

Output

longVariable : 10
doubleVariable : 10.0

TypeCastDemo.java

public class TypeCastDemo
{

    public static void main(String[] args)
    {
        double doubleVariable = 2898.9999;
        long longVariable = 199;
        int intVariable;

        /*
         * Variable of larger capacity is be assigned to another variable of
         * smaller capacity.
         */
        intVariable = (int) longVariable;

        System.out.println("longVariable " + longVariable
                + " converted to intVariable : " + intVariable);

        intVariable = (int) doubleVariable;

        System.out.println("doubleVariable " + doubleVariable
                + " converted to intVariable : " + intVariable);

    }
}

Output

longVariable 199 converted to intVariable : 199
doubleVariable 2898.9999 converted to intVariable : 2898
