Compile time error is any type of error that prevent a java program compile like a syntax error, a class not found, a bad file name for the defined class, a possible loss of precision when you are mixing different java data types and so on.
A runtime error means an error which happens, while the program is running. To deal with this kind of errors java define Exceptions. Exceptions are objects represents an abnormal condition in the flow of the program. It can be either checked or unchecked.

What is the purpose of claiming exceptions?
it informs compiler about its possible exceptions. For example,The purpose of Java exception is to tell the Java runtime system what can go wrong
Describe the JAVA throwable class hierarchy and types of exceptions?
In Java there are two main types of Exceptions. * Checked Exceptions - The ones that can be checked & handled in our code. Ex: I/O Exception, SQL Exception etc. In most cases, the compiler itself forces us to catch & handle these exceptions * Un-checked Exceptions - The ones that we cannot & should not handle in our code. Ex. Null Pointer Exception The java.lang.Throwable is the super class of all errors and exceptions in Java. Only objects of this class can be thrown & caught and handled by try-catch blocks. Ex: try { ..... ..... } catch (Exception e){ ... } finally { ... }
Is error and exception same?
Error: Any departure from the expected behavior of the system or program, which stops the working of the system is an error. Exception:Any error or problem which one can handle and continue to work normally. Note that in Java a compile time error is normally called an "error," while a runtime error is called an "exception." Errors don't have subclasses while exception has two subclasses, they are compile time exception or checked exception (ClassNotFound Exception, IOException, SQLException etc.) and runtime or unchecked exception(ArrayIndexOutOfBounds Exception, NumberFormat Exception).
In order to write compile and execute java programs in my PC which software should i install?
Compilation (byte code conversion) and execution (interpretation) of JAVA programs requires a JAVA Compiler and a JAVA runtime. There are many JAVA development systems available, some free, some not free. Two vendors for the PC / Windows platform are Sun and Microsoft, but, again, there are others.

What is checked exception?
A compiler for the Java programming language checks, at compile time, that a program contains handlers for checked exceptions, by analyzing which checked exceptions can result from execution of a method or constructor. For each checked exception which is a possible result, the throws clause for the method or constructor must mention the class of that exception or one of the superclasses of the class of that exception. This compile-time checking for the presence of exception handlers is designed to reduce the number of exceptions which are not properly handled.

What are tools or software that are needed to editcompile and run to java?
To edit Java source code you can use any text editor. In order to compile a Java source file to Java bytecode you need the Java Development Kit (JDK). The program which does this is called "javac" and can produce .class files which can be used by the Java Runtime Environment (JRE) to execute.

What is java's purpose on my PC?
Programs that are specifically designed with Java require a Java runtime to work on a computer. (In the case of Java, the runtime is called "Java Virtual Machine".) If you have any such program, you need to have Java.
