Splet16. maj 2016 · To swap two string variables without using third or temp variable, we use substring () method of String class. This method has two overloaded forms. 1) substring (int beginIndex) It returns substring of a calling string starting with the character at the specified index and ending with the last character of the calling string. SpletIn the above example, simple mathematics is followed to exchange the value of 3 variables. It involves 4 steps which are mentioned below: Value of num1+ num2+ num3 (i.e. 10 + 20 + 30 = 60) is assigned to variable ‘num1’. So num1 = 60. Value of num1- (num2+ num3) (i.e. 60 – (20+30) = 10) is assigned to variable ‘num2’. So num2= 10.
