Homework SourseHow do I insert a character at a specific index in a string
How do I insert a character at a specific index in a string builder variable?
For example:
StringBuilder temp = new StringBuilder(how to);
I want to insert char \'j\' at temp[3];
Temp would now = howj to.

Solution
public class StringBuilderDemo {
public static void main(String[] args) {
StringBuilder temp = new StringBuilder(\"how to\");
// insert character value at position 3
temp.insert(3, \'j\');
System.out.println(temp.toString());
}
}
/* sample output
howj to
*/
