  • Hi Friends today we will discuss about how to find top two maximum numbers in an array using java program.
  • For this we have written separate function to perform logic
  • findTwoMaxNumbers method takes integer  array as an argument
  • Initially take two variables to find top to numbers and assign to zero.
  • By using for each loop iterating array and compare current value with these values
  • If our value is less than current array value then assign current value to max1 
  • And assign maxone to maxtwo because maxtwo should be second highest.
  • After completion of all iterations maxone will have top value and maxtwo will have second maximum value.
  • Print first maximum and second maximum values.
  • So from main method create array and pass to findTwoMaxNumbers(int [] ar).


Program #1: Java interview programs to practice: find top two maximum numbers in an array without recursion 

  1. package arraysInterviewPrograms.instanceofjava;
  2. public class FindTopTwo {
  3.  
  4. public void findTwoMaxNumbers(int[] array){
  5.        
  6.  int maxOne = 0;
  7.  int maxTwo = 0;
  8.  
  9. for(int i:array){
  10.  
  11.     if(maxOne < i){
  12.            maxTwo = maxOne;
  13.            maxOne =i;
  14.      } else if(maxTwo < i){
  15.                 maxTwo = i;
  16.      }
  17. }
  18.         
  19.  
  20.   System.out.println("First Maximum Number: "+maxOne);
  21.   System.out.println("Second Maximum Number: "+maxTwo);
  22. }
  23.      
  24. public static void main(String a[]){
  25.  
  26.         int num[] = {4,23,67,1,76,1,98,13};
  27.         FindTopTwo obj = new FindTopTwo();
  28.         obj.findTwoMaxNumbers(num);
  29.         obj.findTwoMaxNumbers(new int[]{4,5,6,90,1});
  30.  
  31. }
  32.  
  33. }


Output:


  1. First Maximum Number: 98
  2. Second Maximum Number: 76
  3. First Maximum Number: 90
  4. Second Maximum Number: 6
