else
        if(jTextField1.contains()){ // want to compare it if it's bigger than 9 or not

            jOptionPane1.showMessageDialog(this,"Please enter the number of the tab"); // wich means from 1 to 9

Answer 1

You can directly do it with help of js using jQuery just give id to our text field and add a script tag with the following code :

num = $("#yourId").val();
if(num>9){
alert("your message");
}

or any thing else you want to achieve
