Here's a Java program to convert a double type variable to an int:

public class Main {
    public static void main(String[] args) {
        double d = 10.5;
        int i = (int) d;

        System.out.println("Double value: " + d);
        System.out.println("Integer value: " + i);
    }
}

In this program, we first initialize a double variable d with the value 10.5. We then use a typecast operator (int) to convert d to an int and assign the result to an int variable i.

Finally, we print out the original double value and the converted int value.

The output of this program will be:

Double value: 10.5
Integer value: 10

Note that when converting a double to an int, the decimal part is truncated, which means that the value is rounded down to the nearest integer. If you want to round to the nearest integer, you can use the Math.round method to first round the double value, and then convert it to an int.
