Write a java program to accept a name of college and change case of each alphabet using command line arguments.

class CommandLine
{
public static void main(String args[ ])
{
String str1 = args[0];
StringBuffer newStr=new StringBuffer(str1);
for(int i = 0; i < str1.length(); i++) {
//Checks for lower case character
if(Character.isLowerCase(str1.charAt(i))) {
//Convert it into upper case using toUpperCase() function
newStr.setCharAt(i, Character.toUpperCase(str1.charAt(i)));
}
//Checks for upper case character
else if(Character.isUpperCase(str1.charAt(i))) {
//Convert it into upper case using toLowerCase() function
newStr.setCharAt(i, Character.toLowerCase(str1.charAt(i)));
}
}
System.out.println("String after case conversion : " + newStr);
}
}

Output :
