Example 1: how to change double to int in java

        double decimal = 5.7;
        System.out.println( (int) decimal );	//casting
        System.out.println( Math.round(decimal * 10) / (double) 10);	//Math.round()
        System.out.println( decimal % 1);	// modulus
        System.out.println( Integer.parseInt( String.valueOf(decimal).substring(0, String.valueOf(decimal).indexOf(".")))); // .substring()
    }
}

Example 2: convert double into integer

        int IntValue = (int) DoubleValue;
        System.out.println(DoubleValue + " is now " + IntValue);
    }
}
