- 2. What do you understand by Literals? Put down Integer literals and Floating-point literals in detail.
- Meaning of Literals
- Explaining the details of Integer literals and Floating-point literals
Answer:In computer science, a literal is a notation for representing a fixed value in source code. Almost all programming languages have notations for atomic values such as integers, floating-point numbers, and strings, and usually for booleans and characters; some also have notations for elements of enumerated types and compound values such as arrays, records, and objects. An anonymous function is a literal for the function type.
- 3. How is file read by using Buffered Output Stream?
Answer:In our previous discussions we came across ‘Byte Streams’ and ‘Character Streams’ in Java. In this particular blog we will dive into ‘Buffered Streams’. We will come to know how to read from and write to a file in java using ‘Bufferd Streams’ and why this is a good practice to use buffered streams over byte and character streams.In case of ‘byte’ and ‘character’ streams every byte or piece of data that s being read or write requires an direct support from underlying OS because of not having an intermediate buffer included. This makes a extensive use of memory and resources. On the other hand Buffered streams works as a
- 4. Elaborate on the try and catch Blocks, its processes and codes.
- Describing the try and catch Blocks
- Explaining the processes
- Writing the codes
Answer:You see it all over in Java examples and code: EmptyCatchClauses;
try {
someObject.something();
} catch(Exception e) {
// should never happen
}
Either code can handle the exception, then the
- 5. Write notes on:
- The java.sql Package
Answer: java.sql: java.sql is an API to access and process the data stored in a database, typically a relational database using the java. Different drivers can be installed dynamically for the access of various databases, using a framework which in-built in this JDBC API.
The java.sql package contains the entire JDBC API that sends SQL (Structured Query Language) statements to relational databases and retrieves the results of executing those SQL statements. Figure 18-1 shows the class hierarchy of this package. The JDBC 1.0 API became part of the core Java API in Java 1.1. The JDBC 2.0 API supports a variety of new features and is part of the Java 2 platform.
- The javax.sql Package
Answer: javax.sql: javax.sql is a JDBC API for the server side for accessing and processing the data from the databases typically a relational database using java. It is the essential part for J2EE. This API provides the facilities such as connection pooling, distributed transactions and row sets for the enterprise applications. An interface by name DataSource is provided in this API as an alternative to DriverManager to establish the connection.
- 6. Create Simple JSP Pages with proper java application.
Answer:A JSP document is a JSP page written in XML syntax as opposed to the standard syntax described in Chapter 5, JavaServer Pages Technology. Because it is written in XML syntax, a JSP document is also an XML document and therefore gives you all the benefits offered by the XML standard:
- You can author a JSP document using one of the many XML-aware tools on the market, enabling you to ensure that your JSP
