Question

Output all combinations of character variables a, b, and c. If a = 'x', b = 'y', and c = 'z', then the output is: xyz xzy yxz yzx zxy zyx Note: If outputting multiple character variables with one statement, the argument for System.out.print() should start with "" + Your code will be tested in three different programs, with a, b, c assigned with 'x', 'y', 'z', then with '#', '$', '%', then with '1', '2', '3'.

Answer 1

Answer:

// package

import java.util.*;

// class definition

class Main

{

   // main method of the function

public static void main (String[] args) throws java.lang.Exception

{

   try{

       // initialize variables

       char a='x',b='y',c='z';

       // char variables with different Characters

      // char a='#',b='$',c='%';

      // char a='1',b='2',c='3';

       

       // print all the combinations

       System.out.print(""+a+b+c+" "+a+c+b+" "+b+a+c+" "+b+c+a+" "+c+a+b+" "+c+b+a);

   }catch(Exception ex){

       return;}

}

}

Explanation:

Declare and initialize variables a,b,c with "x","y","z" respectively.

Then with the help of print statement we can print all combinations

of these characters.Similarly we can check this for different input

characters.

Output:

xyz xzy yxz yzx zxy zyx

#$% #%$ $#% $%# %#$ %$#
