n Java, the statement x++ is exactly equivalent to x = x + 1. But if x is a char, it's not exactly the same! In that case, x++ is legal, but x = x + 1 causes an error. write a java code with the error message what it is going to print.

Create a Java program named StringTest.java and write a main method that contains expressions that combinevarious types using the + operator. For example, what happens when you add " a String and a char?(a)Does it perform character addition or string concatenation? (b)How can you determine the type of the result?
A rational number is a number that can be represented as the ratio of two integers. For example, 2=3 is a rational number, and you can think of 7 as a rational number with an implicit 1 in the denominator.a)Define a class called Rational. A Rational object should have two integer instance variables that store the numerator and denominator.b)Write a constructor that takes no arguments and that sets the numerator to 0 and denominator to 1.c)Write an instance method called printRational that displays a Rational in some reasonable format.
