Analyze the following code:
user100 [1]

Answer:

Constructor issue

Explanation:

When you look at the Class A, the constructor takes one argument as a parameter, a String.

A(String newS) {

s = newS;

}

However, in the main, the constructor does not take any argument as a parameter.

A a = new A();

That's why the code does not compile.
