Java Program without main () Function

This blog based on Java Program, without main ().

Introduction 

 

This blog based on Java Program, without main (). Java is a class-based object-oriented programming language.

  

Example

class Math {
 Static {
  int a, b, c;
  a = 12;
  b = 5;
  c = a + b;
  if (c == a + b) {
   System.out.println("a+b\t" + c);
   c = a - b;
   if (c == a - b) {
    System.out.println("a-b\t" + c);
    c = a * b;
    if (c == a * b) {
     System.out.println("a*b\t" + c);
     c = a / b;
     if (c == a / b) {
      System.out.println("a/b\t" + c);
     } else {
      System.out.println("No result");
     }
    }

Create this program in notepad and open CMD and got to the location where your program has save as like suppose desktop then type cd desktop then you see CMD

 

 

Then my program file save in a new folder like java prog so then I command use cd java prog then seen CMD.

 

Then seen output use command for compile java program.

 

Javac math.java

  

When compile program then automatically generate class file go to java prog folder or own location where you save math.java program.

 

It compiles successfully no any error.

 

After that run, the java program uses command java and class name …as like this.

 

Java math

 

Seen CMD for output.

 

 

Finally, no any error compiles and run time … the only exception after rum and output but before not any exception…
