Java sba
Tina and Louis play a game where one has to tell a word and a letter from that word and other has to find an occurrence of that letter(Case Sensitive)in the word and change the Case.
For instance,if the given letter present in the word is in Lowercase then the same should be converted to Uppercase and vice versa and hence display the output.
If the input string is less than 3,then display "String length of <string> is too short" and terminate the program.If the input string is greater than 10, then display "String length of <string> is too long" and terminate the program.
If the input string length is valid, then the input String should contain only alphabets , else display it as "String should not <special character/numbers> and terminate the program.
If the given character(input 2) is not present in the input string(input 1) then display it as "Character <input 2> is not found" .
Develop a java application to check the rules of the game and print the output word as given in the sample input/output.
Assumption:
- Input string(input 1) must be one string without space.
- Character(input 2) must be only alphabet(in Lowercase).
Note:
In the sample Input/output provided the highlighted text in bold corresponds to input provided by the user and rest of the text represents output.
Adhere to the code template if provided.
Sample Input 1:
HapPy
p
Sample output 1:
HaPpy
Explanation:-
Here the letter to be converted is p,in the given string p occurs twice as third character(p) and fourth character(P).
The third and fourth character cases have to be changed from lower to upper case and upper to lower case respectively.
Hence the output is HaPpy.
Sample Input 2:
H
Sample output 2:
String length of H is too short
Sample Input 3:
ArcHitectuRe
Sample output 3:
String length of ArcHitectuRe is too long
Sample Input 4:
HorSe
y
Sample output 4:
Character y is not found
Sample Input 5:
Shi%21
Sample output 5:
String should not contain %21
Solution:
import java.util.*;
public class Main
{
public static void main (String[] args) throws java.lang.Exception
{
Scanner sc = new Scanner(System.in);
String s = sc.nextLine();
StringBuilder str = new StringBuilder(s);
String s1=s.toLowerCase();
char c = sc.next().charAt(0);
Int a=s1.indexOf(c);
StringBuffer
num = new StringBuffer(), special = new StringBuffer();
for (int i=0; i<s.length(); i++)
{
if (Character.isDigit(s.charAt(i)))
num.append(s.charAt(i));
else if(Character.isAlphabetic(s.charAt(i)))
{
/*If output not required to alpha+numeric seperately but required to orint in order having exactly as input then remove 1st if and make this as 1st if*/
}
else
special.append(s.charAt(i));
}
Int b=num.length()+special.length();
if(b>0) {
System.out.println("String should not contain "+special+num);
System.exit(0);
}
else if(s.length()>10) {
System.out.println("String length of "+s+" is too long");
System.exit(0);
}
else if(s.length()<3) {
System.out.println("String length of "+s+" is too short");
System.exit(0);
}
E
else if (a<0)
{
System.out.println("Character "+c+" is not found");
System.exit(0);
}
else If(a>=0)
{
if(Character.isUpperCase(s.charAt(a))) //return true if UpperCase
str.setCharAt(a,Character.toLowerCase(s.charAt(a)));
else
str.setCharAt(a,Character.toUpperCase(s.charAt(a)));
Int n2=s1.indexOf(c,a+1);/*if there are more than two occurence of passed character in testcase1 write code for n3 n4 as much as need same as code for n2 */
If(n2>0)
{ if(Character.isUpperCase(s.charAt(n2))) //return true if UpperCase
str.setCharAt(n2,Character.toLowerCase(s.charAt(n2)));
else
str.setCharAt(n2,Character.toUpperCase(s.charAt(n2)));
} System.out.println(str);
}
}
}
