In this core java programming tutorial we will write a program to Find subArray in array whose sum matches required sum in java.
Write a program to find out duplicates in array in one iteration.
Example/ Full Program/SourceCode to Find duplicates in array in one iteration in java >
/** Copyright (c), AnkitMittal JavaMadeSoEasy.com */
public class FindDuplicateInOneIterationExample{
static int ar[]={3,7,3,5,8,9,24,8,9}; //given array
public static void main(String[] args) {
System.out.print("array : ");
for (int j = 0; j < ar.length; j++)
System.out.print(ar[j] +" "); // display it
displayDuplicateInOneIteration();
}
/*
* Method for displaying duplicate in one iteration
*/
static public void displayDuplicateInOneIteration(){
int tempAr[]=new int[100];
System.out.print("\nduplicates : ");
for (int j = 0; j < ar.length; j++){ /*make indexes of tempAr corresponding to value found in ar equal to 1.
i.e if i[0]=22, than make tempAr[22]=1;
if i[1]=25, than make tempAr[25]=1; */
if(tempAr[ar[j]]==0){
tempAr[ar[j]]=1;
}
else{
System.out.print(ar[j]+" ");
}
}
}
}
/*OUTPUT
array : 3 7 3 5 8 9 24 8 9
duplicates : 3 8 9
*/
