Print Numbers

Back to the Program-A-Day homepage

Problem Write a method which will take 3 ints as parameters. The method should print the elements in order, separated by a comma. Example: printNumbers(5, 7, 4); Output:4,5,7		Static Methods
Solution You should split this up into three methods which print out the smallest, middle and largest numbers. public static void printSmallest( int n1, int n2, int n3 ); public static void printMidNum( int n1, int n2, int n3 ); public static void printLargest( int n1, int n2, int n3 ); You will need to use if statements to determine the proper order to print out the numbers. if( n1 <= n2 && n1 <= n3 ) { System.out.print( n1 ); } else if( n2 <= n3 ) { System.out.print( n2 ); } else { System.out.print( n3 ); } and similarly for the middle and largest numbers.
Code Solution Code public static void printNumbers( int n1, int n2, int n3 ) { printSmallest( n1, n2, n3 ); System.out.print( "," ); printMidNum( n1, n2, n3 ); System.out.print( "," ); printLargest( n1, n2, n3 ); } public static void printSmallest( int n1, int n2, int n3 ) { if( n1 <= n2 && n1 <= n3 ) { System.out.print( n1 ); } else if( n2 <= n3 ) { System.out.print( n2 ); } else { System.out.print( n3 ); } } public static void printMidNum( int n1, int n2, int n3 ) { if( n1 >= n2 && n1 <= n3
