Find top two maximum numbers in a array java

  • 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 

package arraysInterviewPrograms.java;
public class FindTopTwo {
public void findTwoMaxNumbers(int[] array){
       
 int maxOne = 0;
 int maxTwo = 0;
for(int i:array){
    if(maxOne < i){
           maxTwo = maxOne;
           maxOne =i;
     } else if(maxTwo < i){
                maxTwo = i;
     }
}
        
  System.out.println("First Maximum Number: "+maxOne);
  System.out.println("Second Maximum Number: "+maxTwo);
}
     
public static void main(String a[]){
        int num[] = {4,23,67,1,76,1,98,13};
        FindTopTwo obj = new FindTopTwo();
        obj.findTwoMaxNumbers(num);
        obj.findTwoMaxNumbers(new int[]{4,5,6,90,1});
}
}


Output:


First Maximum Number: 98
Second Maximum Number: 76
First Maximum Number: 90
Second Maximum Number: 6
