Java program to replace certain characters from string without using predefined methods.

Question

How can we do this with the help of array?

Answer 1

It is possible, if you use a String array, loop through it, search for equality and replace those chars by assigning a new value to the element.
But it is recommended to use equals method to check equality for good reasons, so this is not safe.

Answer 2

@Empty
