One option is to cast it to an int. Another option is to use the Double wrapper class and call its intValue() method:

public class DoubleToInt {

  public static void main(String[] args) {
    double doubleValue = 13.4;
    System.out.println("Double value: " + doubleValue);

    // casting to an int
    int intValue = (int) doubleValue;    
    System.out.println("Int value: " + intValue);

    // using the Double wrapper class 
    Double doubleObject = doubleValue;
    intValue = doubleObject.intValue(); 
    System.out.println("Int value: " + intValue);
  }
}
