2. If you compile a class without errors but with warnings, a .class file is created.

3. If you compile a class with errors, a .class file is created for the class.

4. If you compile an interface without errors, but with warnings, a .class file is created for the interface.

Explanation / Answer

For compliling java files ,do remember following simple rule :

With this knowledge ,evaluation of given option is as :

1. If you compile an interface without errors, a .class file is created for the interface.

Interface is also a java file ,it would also generate a class file with name of interface as Class file name ,after

its compilation . so this statement is correct .

2. If you compile a class without errors but with warnings, a .class file is created.

Class file with java extension would also generate a Class file with name of Class after its compilation ,so this

statement is also correct.

3. If you compile a class with errors, a .class file is created for the class.

A class with errors would not compile as it would generate errors and so a class file is not generated . So ,this

statement is not correct .

4. If you compile an interface without errors, but with warnings, a .class file is created for the interface.

A class file with warnings would get compiled and will generate a Class file with name as the Class inside the class file . So this statement is also correct.

So , for this question ,options 1, 2 and 4 are correct .
