Another version of this method is int indexOf (String str) It is same as above except that it accepts a string argument. For example, s3.indexOf(“there”) will return 6 i.e. the index position of the first occurrence of substring “there” in the string. int indexOf (int ch, int...
Identity strings are particularly useful in scenarios where object equality based on content is not sufficient, such as in debugging (object tracking), distributed systems, or caching. For example, two Java objects may have the same state, but if they are separate instances, they will have diffe...

For example: char firstChar = str.charAt(0); char secondChar = str.charAt(1); Get the last character in a string. Use charAt() again, but use the list index in the string, which is equal to the length minus one (because indexes start at zero): char lastChar = str.charAt(...
