But again, in ur code, u took the help of an inbuilt method isLowerCase()...
Inorder to achieve without that we have to put condition like (65=<c<=90 then add logic to convert to lower case ) and (97 =<c<=122 then write uppercase logic)

[miralkhunt]

If there is any other characters in string other than alphabets then it will add 32 in that character's ASCII value and set the character according to that value.

Basically else part will be executed.

[pruthvirajn]

If it contains number, then it will check for that number correspondingly what is the asic value then it will add and print respected value.

Can you please write program to calculate & list n prime numbers in Java 8 streams

[ashishsingh]

it will not work because every integer is some ascii value and integer has no uppercase or lowercase

[animff]

QUESTION FOR AUDIENCE? THE ANSWER IS = that will put another else condition and then and there we will do str = str +c

[satishbhutawale]

package com.method;

public class LowerUpper
{
public static void main(String[] args) {
String str="CloudTech";
String newstr="";
char[] array = str.toCharArray();

for(int i=0;i<array.length;i++)
{

{

}
else
{

}
}

}
}
