Why toString is used in Java?
What is the purpose of toString() method in Java? If we want to represent an object of a class as a String, then we can use the toString() method which returns a textual representation of the object. When you print an object, by default the Java compiler invokes the toString() method on the object.

What is @override in Java?
The @Override annotation is one of a default Java annotation and it can be introduced in Java 1.5 Version. It extracts a warning from the compiler if the annotated method doesn’t actually override anything. It can improve the readability of the source code.

The default toString() method in Object prints “class name @ hash code”. We can override the toString() method in our class to print proper output. For example, in the following code toString() is overridden to print the “Real + i Imag” form.
What is toString X2?
It formats the string as two uppercase hexadecimal characters. In more depth, the argument “X2” is a “format string” that tells the ToString() method how it should format the string. In this case, “X2” indicates the string should be formatted in Hexadecimal.
What is the difference between int parse and convert ToInt32?
In brief, int. Parse and Convert ToInt32 are two methods to convert a string to an integer. The main difference between int Parse and Convert ToInt32 in C# is that passing a null value to int Parse will throw an ArgumentNullException while passing a null value to Convert ToInt32 will give zero.
What is float parse?
The parseFloat() method in Float Class is a built in method in Java that returns a new float initialized to the value represented by the specified String, as done by the valueOf method of class Float.
What is BigDecimal toplainstring() method in Java?
