what is diffrent between get vs post vs put vs delete?

Question

i'm new in rest and confuse about http methods like get,post,put,delete,option,head can any one please share me simple example.

here is my example:

@GET 
    @Produces("text/plain")
    public String getIt() {
        return "Hi there!";
    }

    @DELETE
    @Produces("text/plain")
    @Path("/getItDelTest")
    public String getItDelTest()
    {
        return "Hi there is getITDelTest method";
    }

    @HEAD
    @Produces("text/plain")
    @Path("/getItHeadTest")
    public String getItHeadTest()
    {
        return "Hi there is getITHeadTest method";
    }

    @PUT
    @Produces("text/plain")
    @Path("/getItPutTest")
    public String getItPutTest()
    {
        return "Hi there is getITPutTest method";
    }


    @POST
    @Produces("text/plain")
    @Path("/getItPost")
    public String getItPost()
    {
        return "Hi there is getItPost method";
    }

above this example i'm just create a simple method with diffrent-2 nature but i don't understand why we need all that if we able to do all these action with post

The GET method is meant for data retrieval only and should not have any side-effects. But POST is meant for that specific purpose: altering data on the server side.

To change the state of a resource or to update it, use PUT and To remove or delete a resource, use DELETE..

The difference is based on the HTTP Action verb. This verb is contained within the actual HTTP message. The handling of these verbs is implementation specific. For example in C# I can have 2 Web API methods named Hello in the same controller. One could be mapped to the GET and the other to the PUT or DELETE etc....

what is diffrent between get vs post vs put vs delete?
