We have three country buttons, if we click any button that country information should only display?

Apex:

public class coun {

    public Boolean hide = false;

    public Boolean hide1 = false;

    public Boolean hide2 = false;

    

    public void setMhide(Boolean b) {

    this.hide = b;

    }

    

    public Boolean getMhide() {

    return this.hide;

    }//Passing input dynamically through another method

    

    

    public Boolean getM1hide() {

        return this.hide2;

    }

    

    public void setM1hide(Boolean b) {

      this.hide2 = b;  

    }

    

    

    public Boolean getM2hide() {

        return this.hide1;

    }

    

    public void setM2hide(Boolean b) {

        this.hide1 = b;

    }

    

    

    public PageReference india() {
        setMhide(true);
        setM2hide(false);
        setM1hide(false);     
        return null;
    }//displaying only india information and hiding other information

    

     public PageReference us() {

        setM1hide(true);

        setM2hide(false);

        setMhide(false);

        return null;

    }

    

    public PageReference uk() {

        setM2hide(true);

        setM1hide(false);

        setMhide(false);

        return null;

    }   

    

}
