Question
What will be the result of compiling and runnig the following code:public class Test{ public static void main(String... args) throws Exception{ Integer i = 34; int l = 34; if(i.equals(l)){ System.out.println("true"); }else{ System.out.println("false"); } }} truefalseCompiler error None of these
Solution
The result of compiling and running the provided Java code will be "true".
Here's the step by step explanation:
-
The code defines a class named
Test. -
Inside the
Testclass, it defines amainmethod which is the entry point for any Java program. -
Inside the
mainmethod, it creates anIntegerobjectiwith a value of34. -
Then it declares a primitive
intvariablelwith a value of34. -
It then checks if
iis equal tolusing theequalsmethod. In Java, theequalsmethod is used to compare the values of two objects for equality. In this case, it's comparing anIntegerobject with a primitiveint. -
Java automatically converts the primitive
intto anIntegerobject before the comparison (this is called autoboxing), so theequalsmethod compares twoIntegerobjects with a value of34. -
Since both
Integerobjects have the same value, theequalsmethod returnstrue. -
Therefore, the
ifcondition istrueand "true" is printed to the standard output.
So, the output of the program is "true".
