Question

Accepted Answer

Explains difference between string object, string literal and string buffer. Also, sorts array and finds pair of numbers.

String object is an instance of a class, string literal is a sequence of characters enclosed in double quotes, and string buffer is a mutable sequence of characters.
To sort an array of strings, use Arrays.sort() method.
To find a pair of numbers in an array that add up to a target value, use a nested loop to compare each element with every other element.
Example: String str = new String('hello'); String literal = 'world'; StringBuffer sb = new StringBuffer('Java');
Example: Arrays.sort(arrayOfStrings); for(int i=0; i
