πŸ‘‰πŸΏπŸ’» Secured

Java is best known for its security. With Java, we can develop virus-free systems. Java is secured because:

βž– No explicit pointer
βž– Java Programs run inside a virtual machine sandbox
βž– Classloader: Classloader in Java is a part of the Java Runtime Environment(JRE) which is used to load Java classes into the Java Virtual Machine dynamically. It adds security by separating the package for the classes of the local file system from those that are imported from network sources.
βž– Bytecode Verifier: It checks the code fragments for illegal code that can violate access right to objects.
βž– Security Manager: It determines what resources a class can access such as reading and writing to the local disk.

Java language provides these securities by default. Some security can also be provided by an application developer explicitly through SSL, JAAS, Cryptography, etc.

Types of Variables in Java
Now let us discuss different types of variables which are listed as follows:

1.Local Variables
-A variable defined within a block or method or constructor is called a local variable.

2.Instance Variables
-Instance variables are non-static variables and are declared in a class outside any method, constructor, or block.

3.Static Variables
-Static variables are also known as Class variables.
* These variables are declared similarly as instance variables. The difference is that static variables are declared using the static keyword within a class outside any method constructor or block.

INLINE FUNCTION [ C++]


//Inline Function example

#include<iostream.h>
#include<conio.h>
class line
{
public:
inline float mul(float x,float y)
{
return(x*y);
}
inline float cube(float x)
{
return(x*x*x);
}
};
void main()
{
line obj;
float val1,val2;
clrscr();
cout<<"Enter two values:";
cin>>val1>>val2;
cout<<"\nMultiplication value is:"<<obj.mul(val1,val2);
cout<<"\n\nCube value is :"<<obj.cube(val1)<<"\t"<<obj.cube(val2);
getch();
}

Output:

Enter two values:10 20

Multiplication value is:200

Cube value is :1000 8000

PALINDROME NUMBER [ JAVA]



import java.util.*;

class Palindrome
{
public static void main(String args[])
{
String original, reverse="";
Scanner in = new Scanner(System.in);

System.out.println("Enter a string to check if it is a palindrome");
original = in.nextLine();

int length = original.length();

for ( int i = length - 1 ; i >= 0 ; i-- )
reverse = reverse + original.charAt(i);

if (original.equals(reverse))
System.out.println("Entered string is a palindrome.");
else
System.out.println("Entered string is not a palindrome.");

}
}


Output:

Enter a string to check if it is a palindrome
45654
Entered string is a palindrome.
