The static variable can be used to refer to the common property of all objects (which is not unique for each object), for example, the company name of employees, college name of students, etc. The static variable gets memory only once in the class area at the time of class loading.

class JavaKA
{
static String course=”java”;
void notes()
{
System.out.println(course);
}
String computer()
{
String course =”html”;
System.out.println(course);
return course;

}
public static void main(String args[]){
JavaKA m=new JavaKA();
m.notes();
m.computer();
//System.out.println(course);
}
}

Why we should learn static ?

The most important reason why static keywords are heavily used in Java is to efficiently manage memory

Without creating object, we can directly call from the class name

Today we learnt about control statement. The control statements are if else using this we did a program

my program is:

class sasi{
public static void main(String args[]){
int x=10;
int y=5;
if(x>y)
{
System.out.println(“true”);
}
else
{
System.out.println(“false”);
}
}
}

Java compiler executes the code from top to bottom. The statements in the code are executed according to the order in which they appear. However, Java provides statements that can be used to control the flow of Java code. Such statements are called control flow statements. It is one of the fundamental features of Java, which provides a smooth flow of program.

If statement:

The Java if statement is the most simple decision-making statement. It is used to decide whether a certain statement or block of statements will be executed or not i.e if a certain condition is true then a block of statement is executed otherwise not.

else statement:

The ELSE statement specifies that alternate processing is to take place when the conditions of the matching IF statement are not satisfied. ELSE. The ELSE statement has no parameters. The ELSE statement must be column-aligned with the matching IF statement.

Today class is about final parameters. final parameter defines if we to keep the things constant ,then final parameter will be used.

We got lots of doubt in it. Sir make as out of clarification.

You can pass final variables as the parameters to methods in Java. A final variable can be explicitly initialized only once. A reference variable declared final can never be reassigned to refer to a different object. However, the data within the object can be changed.So, the state of the object can be changed but not the reference. With variables, the final modifier often is used with static to make the constant a class variable.

public class Test{
   public void sample(final int data){
      System.out.println(data);
   }
   public static void main(String args[]) throws Exception{
      Test t = new Test();
      t.sample(500);
   }
}

Today I miss my java class due to I got sick. But my friends thought me my missed class. Two of my friends helped me. Today class was full of Data Types Data Type consist of int, byte, long, double, float, short, string, char, boolean

Also we thought with binary and decimal number. I have doubt on that topic but friends figure it out.

Today I installed linux. The experience was terribly bad I literally suffered lots. Unfortunately my system was very slow. Me and one my friends tried hard for the installation.

somedays we keep on trying for the good result and once we get it so, will be very happy . I actually felt the same while installing linux on my computer

Hi this is sobhika , in my first day in payilagam I came to that my upcoming days in payilagam will be good and more unerstanding with my new friends. The motivation of Muthu sir inspires us really.
