Write a program to input a sentence and convert it into uppercase and count and display the total number of words starting with a letter ‘A’.
Example:
Sample Input: ADVANCEMENT AND APPLICATION OF INFORMATION TECHNOLOGY ARE EVER CHANGING.

A tech number has even number of digits. If the number is split in two equal halves, then the square of sum of these halves is equal to the number itself. Write a program to generate and print all four-digit tech numbers.
Example :
Consider the number 3025
Square of sum of the halves of 3025 = (30+25)2
= (55)2
= 3025 is a tech number.

State the output when the following program segment is executed:
String a = "Smartphone", b = "Graphic Art";
String h = a.substring(2, 5);
String k = b.substring(S).toUpperCase();
System.out.println(h);
System.out.println(k.equalsignoreCase(h)); Design a class to overload a function Joystring( )as follows:
(i) void Joystring (String s, char ch1 char ch2) with one string argument and two character arguments that replaces the character argument ch1 with the character argument ch2 in the given string s and prints the new string.
Example:
Input value of s = “TECHNALAGY”
ch1=‘A’,
ch2=‘O’
Output: TECHNOLOGY
(ii) void Joystring (String s) with one string argument that prints the position of the first space and the last space of the given string s.
Example:
Input value of = “Cloud computing means Internet based computing”
Output: First index: 5
Last index: 36
(iii) void Joystring (String s1, String s2) with two string arguments that combines the two string with a space between them and prints the resultant string. Example :
Input value of s1 =“COMMON WEALTH”
Input value of s2 =“GAMES”
Output: COMMON WEALTH GAMES
