Related to variables

#1

in this quistion i didnt understand how can we return i and z compilar is asking for local variables

#2

hey @missroy I hope this will help.

  • Problem statement is quite easy you just need to tell whether the character entered is Lower case or Uppercase otherwise print I.
  • We can also compare characters directly without remembering the ascii codes.

Code

public static char tell(char ch) {
        if(ch >= 'a' && ch <= 'z')
            return 'L';
        else if(ch >= 'A' && ch <= 'Z')
            return 'U';
        else
            return 'I';
}

why we are taking &gt reference variable here

#4

hey @missroy because we are comparing whether the current character lies within small alphabets or capital alphabets

hey @missroy is a Bitwise AND logical operator.It will do the work of AND gate.

this is my code import java.util.*; public class Main { public static void check(char ch) { if (ch >= ‘A’ && ch <= ‘Z’) { return ‘U’ ; } else if(ch >=‘a’ && ch <= ‘z’) { return ‘L’; } else { return ‘i’; } } public static void main(String []args) { char ch; Scanner s=new Scanner(System.in); ch=s.next().charAt(0); check(ch); } }

hey @missroy I have corrected your mistakes //Look for comments in between the code to see what was the mistake.
import java.util.*;

public class Main {
//here return type should be char bcoz you are returning char.
public static char check(char ch) {
if(ch >= ‘a’ && ch <= ‘z’)
return ‘L’;
else if(ch >= ‘A’ && ch <= ‘Z’)
return ‘U’;
else
//here I should be capital.
return ‘I’;
}

public static void main(String[] args) {
	Scanner s = new Scanner(System.in);
	char ch = s.next().charAt(0);
	//here  I have called the method from sysO statement bcoz we need to print the output given by it.
System.out.println(check(ch));
}

}
