The given task is to print a ‘;‘ without using ‘;‘ anywhere in the code. The simplest idea one can think of to approach this interesting question is using ASCII value somehow in the program. But as Java does not support macros, unlike C/C++, therefore to eliminate ‘;’ at the end of every line in code is to use, if-statement or while loop with printf(String, Object) method of PrintStream in the condition statement. The main logic here is as printf() returns PrintStream object which is not null so on comparison it with null (literal in Java) we will get our desired output.
Method 1: Using if statement
Java
// Java program to print ; without using ;// using if statementclass PrintSemicolonExample { public static void main(String[] args) { // The ASCII value for semicolon is 59 if (System.out.printf("%C", 59) == null) { } }} |
Output
;
Method 2: Using while loop
Java
// Java program to print ; without using ;// using while loopclass PrintSemicolonExample { public static void main(String[] args) { while ((System.out.printf("%C", 59) == null)) { } }} |
Output
;
Time complexity: O(1)
Auxiliary space: O(1)
