For the following Questions The required keyboard IO stateme

For the following Questions: The required keyboard I/O statements are predefined as: import javax.swing. JOptionPane Import java.util.Scanner; Scanner kB = new Scanner You have created a java source program: MyProg.java To compile the program under DOS - Write down the compilation command Suppose there is no syntax error, what will be the file name of the O/P created by the compiler? What is the command you will use to execute the program? ANS (1): ANS (2): ANS (3): Write one console O/P statement in one line without any literals to display the following sentences in 4 lines by using the variable definitions as these: String s1 = \"I like Java very much \'n\"; String s2 = \"Java is powerful, interesting and easy to learn \'n\"; String s3 = \" I made a commitment to myself that I shall master this technology to matter what, \'n\"; String s4 = \"I am inspired profoundly by my professor that with this technology in my mind it shall benefit all my life, \"n\"; Write one GUI O/P statement in one line without any literals to display the following sentences in 4 lines by using the variable definitions as these String s1 = \" I like Java very much, n\"; String s2 = \"Java is powerful, interesting and easy to learn \'n\"; String s3 = \" I made a commitment to myself that I shall master this technology to matter what, \'n\"; String s4 = \"I am inspired profoundly by my professor that with this technology in my mind it shall benefit all my life, \"n\"; Write one console O/P statement without any literals to display the following lines of words using the Strings variables defined below: A variable declared within a method definition is called a local variable. Are these local variable(s) available to other method(s)? ANS: circle Yes or No

Solution

1. Ans 1. javac MyProg.java will compile the code.

Ans 2. MyProg.class is the output created by the compiler.

Ans 3. java MyProg will execute the code.

2. System.out.println(s1 + s2 + s3 + s4); will do the needful.

3. JOptionPane.showMessageDialog(null, s1+s2+s3+s4); will do the needful.

4. System.out.println(t1 + t2 + \"\\t\" + t3 + \"\\t\" + t4 + \"\\t\" + t5 + \"\\t\" + \"Final\ \" + t6); Note that we can\'t achieve this without using any literals.

5. No. The local variables are local to a method, and are not available outside the method.
