Here num1 is id for the textbox and we are just giving a variable name ‘e1’ to text box with id ‘num1’. Similarly, we have to use the same statement for the second textbox with the variable name ‘e2’. For the third text box, we have used 'TextView t1=(TextView) findViewById(R.id.result) ' Open the MainActivity.java file there within the class, and make a method named doSum(View v). In this method, first of all, we have to link two EditText with variables so that we can use them for our input. So link those edit box with variables we have written 'EditText e1=(EditText )findViewById(R.id.num1) ' Step 3: Working with the MainActivity.java file Split() String method in Java with examplesĪfter using this code the UI will be like as follows:.Producer-Consumer solution using threads in Java.Method and Block Synchronization in Java.Naming a thread and fetching name of current thread in Java.What does start() function do in multithreading in Java?.Java Concurrency – yield(), sleep() and join() Methods.
