Suppose there is a String.
Say, String test="My name is debasish";
Now I want to edit any one character.
Say, I want to edit the seventh character, e to c.
How can I achieve this?
One method is to change the string to an character array.
But I want to know if there is any other way to achieve this...

If you are using java 1.5 or later, go with String.format. String concatenation costs more memory.

Thanks for posting this, I have taken JAVA, and I'm always looking for valid information such as this.
