![]() PreparedStatement pstmt = con.prepareStatement(query) String query = "INSERT INTO Emp(Name, String, Location) VALUES (?, ?, ?)" ![]() You can insert the same record using the PreparedStatement as follows. Stmt.execute("INSERT INTO Emp VALUES ('Amit', '1-9-1989', 'Vishakhapatnam')") You can insert data to the EMP table using SQL statements as follows. Therefore, to reduce the communication overhead, batch processing is used.įor example, consider the table Emp with the below description. As a result, the communication overhead increases between the database and the program. Generally, when you execute SQL statements one after the other, the execution simultaneously switches from the database to the program.

Therefore, it eliminates the need for compiling the instructions again to provide high performance. JIT will compile that ( XYZ) instruction and keep it in the memory. As a result, the JIT compiler in JVM is developed to check at a run time for the instructions executing multiple times. In such a scenario, traditional JVM will read XYZ instruction, convert it into machine code, and execute it 1000 times. For example, if there is an XYZ instruction in a program that has to be executed more than 1000 times. JVM consists of a Just In Time Compiler (JIT), which compiles the bytecode to machine code at runtime. ![]() Java provides high performance because of its intermediate bytecode. Features like Enterprise JavaBeans (EJB) and Remote Method Innovation (RMI) help users achieve distributed programming. This feature in Java is called distributed programming, mainly used to develop large applications. Programmers sitting on one machine can access all these programs. They can split a program into many parts and store them on different computers. With the Java programming language, users can create distributed applications. However, Java removes the complexities involved in C and C++ programming languages like explicit pointers, storage classes, operator overloading, preprocessors, header files, and more. Since Java is influenced by C and C++ programming, it is simple to understand. Therefore, Java is known as a platform-independent language. Every operating system consists of a different JVM, but the output produced after the byte code execution is the same across all the operating systems. In the running stage, JVM executes this bytecode. It takes the simple Java code as input and gives the bytecode as output. The compilation stage is done by the Java compiler called javac, included in the Java Development Kit (JDK). Java’s execution process consists of Java Virtual Machine (JVM), including writing, compiling, and running program execution stages. Key Features of Java 1) Platform Independent Today, Java can be used to build applications for a wide range of platforms like desktops, servers, mobile phones, tablets, web browsers, and more. Earlier, Java was invented to provide a reliable platform upon which many applications and services can be developed. Since Java is an object-oriented programming language, it supports features like Polymorphism, Inheritance, Data Abstraction, and Data Encapsulation. Member functions are like functions used to define the behavior of objects of the class. The car’s name, color, brake, weight, and more will be its data members. For example, consider the car as an object. Classes are like a prototype from which objects are created, consisting of data members and member functions. ![]() Object-oriented programming language refers to programming languages that use classes and objects. Developed in 1995 by Sun Microsystems, Java is a simple, object-oriented, high-level programming language. ![]()
