double to long

public class DoubleToLong {
   
    public static void main(String args[]){
        
        // first example - converting double to long using longValue() method        
        double d = 102.9520;
        long l = (new Double(d)).longValue();
        System.out.println("double value=" + d + ", long=" + l);
        
        // second example - rather simple just cast double to long
        double bill = 293.05;
        long myBill = (long) bill;
        System.out.println("double value=" + bill + ", long=" + myBill);
               
        
        // third example - rounding double value to long in Java
        double dbl = 3421.56;
        long rnd = Math.round(dbl);
        System.out.println("double value=" + dbl + ", long=" + rnd);
         
    }
}

// Output
// double value=102.952, long=102
// double value=293.05, long=293
// double value=3421.56, long=3422
