Line 1 :  int x = Integer.parseInt("5"); Line 2 :  float pi=Float.parseFloat("3.14"); Line 3 :  boolean status=Boolean.parseBoolean("TRUE");Line 4 :  char c = new Character("X");Which of the above lines can cause compilation error?Select one:a.Line 2b.Line 3c.Line 4d.Line 1

Solution

The line that can cause a compilation error is Line 4.

In Java, you cannot create a new Character object using a String as a parameter. The Character constructor only accepts a single character. The correct way to create a new Character object would be:

char c = new Character('X');

So, the answer is c. Line 4.
