Answer:
FileOutputStream out = new FileOutputStream("ObjectData.dat");
ObjectOutputStream ostream = new ObjectOutputStream(out);
ostream.writeObject(r);
Explanation:
For object serialization, we can use the writeObject method of java.io.ObjectOutputStream class.
The complete code fragment is as follows:
import java.io.*;
class Demo{
public static void main(String args[]){
try{
r = <Reference to Object to be serialized> ;
FileOutputStream out = new FileOutputStream("ObjectData.dat");
ObjectOutputStream ostream = new ObjectOutputStream(out);
ostream.writeObject(r);
ostream.close();
} catch(Exception e){
e.printStackTrace();
}
}
}
Answer:
Explanation:
The code provided had many errors. I fixed the errors and changed the userAgeCheck function as requested. Checking the age of that the user has passed as an input and changing the variables as needed depending on the age. The background color that was changed was for the form field as the question was not very specific on which field needed to be changed. The piece of the code that was created can be seen in the attached image below.
var validColor = "LightGreen";
var invalidColor = "Orange";
var userAgeInput = document.getElementById("userAge");
var formWidget = document.getElementById("userForm");
var userAgeValid = false;
function userAgeCheck(event) {
if ((userAgeInput >= 25) && (userAgeInput <= 35)) {
document.getElementById("userForm").style.backgroundColor = validColor;
userAgeValid = true;
} else {
document.getElementById("userForm").style.backgroundColor = invalidColor;
userAgeValid = false;
}
};
function formCheck(event) {};
if (!userAgeValid) {
userAgeInput.addEventListener("input", userAgeCheck);
formWidget.addEventListener('submit', formCheck);
event.preventDefault();
}
