A simple Java method not working

Hello everyone I am a newbie with the java programming language and have been learning the use of methods, below is a simple method i wrote for adding two numbers but when I run the code, it doe not display any output, please what I am doing wrongly? the code should sum numbers from 2 to 4 in this case

//testing Java methods
    public class Methods {
       public static void main(String [] args) {
         int addition = add (2,4);
         System.out.println(addition);
      }

//the method for addition
      public static int add(int a, int b){
         int sum = 0;
         for (int i = a; a <= b ; i++)
           sum += i;
        return sum;
    }
}

//testing Java methods
public class Methods {
    public static void main(String[] args) {
        int addition = add(2,4);
        System.out.println(addition);
    }

    //the method for addition
    public int add(int a, int b){ // Place this method in the class.
        int sum = 0;
        for (int i = a; i <= b ; i++){ // "a <= b" Has to be: i <= b
            sum += i;
        }
        return sum;
    }
}

I think this is want you want.

The result will be: 2+3+4 = 9

your for loop should be 

for (int i = a; i <= b ; i++)

It was actually running into infinite loop.

try this program (change from a <= b to i <= b)

 public static void main(String[] args) {
        int addition = add(2, 4);
        System.out.println(addition);
    }

    // the method for addition
    public static int add(int a, int b) {
        int sum = 0;
        for (int i = a ; i <= b ; i++) {
            sum += i;
        }
        return sum;
    }

output

9

for (int i = a; a <= b ; i++)

It should be 

 for (int i = a; i <= b ; i++)
