- 2) Read the following main class. Try to guess what will be its output. class Test { public static void main(String s[]) throws Exception { TextThread x = new TextThread ("I am thread x"); TextThread y= new TextThread ("I am thread y"); x.start(); y.start();System.out.println("I am Main thread"); } } 3) Write it and execute it. Is the output convenient with your previous answer? What’s wrong? Complete the code so that all thread execute properly. Answer the third question, please1.class Nothing {public static void main(String args[]){int x = 0;int y = 20;int fraction = y/x;System.out.println("End Of Main");}}1. If there will occur exception, write the code that will handle the exception.4) Read the following second main class. Guess its output. class Test { public static void main(String s[]) throws Exception { TextThread x = new TextThread ("Hello"); TextThread y = new TextThread ("Java"); x.start(); x.join(); y.start(); System.out.println("I am Main thread"); } }
