Write a Java Program to convert primitive types to objects and vice versa

class Main {
public static void main(String[] args) {

// create primitive types
int var1 = 5;
double var2 = 5.65;
boolean var3 = true;

//converts into wrapper objects
Integer obj1 = Integer.valueOf(var1);
Double obj2 = Double.valueOf(var2);
Boolean obj3 = Boolean.valueOf(var3);

// checks if obj are objects of
// corresponding wrapper class
if(obj1 instanceof Integer) {
System.out.println(“An object of Integer is created.”);
}

if(obj2 instanceof Double) {
System.out.println(“An object of Double is created.”);
}

if(obj3 instanceof Boolean) {
System.out.println(“An object of Boolean is created”);
}
}
}

2: Java Program to Convert Wrapper Objects to Primitive Types

class Main {
public static void main(String[] args) {

// creates objects of wrapper class
Integer obj1 = Integer.valueOf(23);
Double obj2 = Double.valueOf(5.55);
Boolean obj3 = Boolean.valueOf(true);

// converts into primitive types
int var1 = obj1.intValue();
double var2 = obj2.doubleValue();
boolean var3 = obj3.booleanValue();

// print the primitive values
System.out.println(“The value of int variable: ” + var1);
System.out.println(“The value of double variable: ” + var2);
System.out.println(“The value of boolean variable: ” + var3);
}
}
