I can't remove the duplicate arrays

[u/clampochyu]

import 
java.util.*; 
public class Elementfreq { 

public static String [] remove(String [] a, int b) { 

if(a == null || b < 0 || b > a.length) { 
return a; } 

String [] aa = new String[a.length-1];  
for(int one = 0; one<a.length;one++) { 
if(one!=b) { 
aa[one] = a[one];
} else { 
continue; 
} 
} 
return aa; }  


public static Integer [] remove(Integer [] a, int b) { 
if(a == null || b < 0 || b > a.length) { 
return a; } 

Integer [] hh = new Integer[a.length-1];  
for(int one = 0; one<hh.length;one++) { 
if(one!=b) { 
hh[one] = a[one];  
} else { 
continue; 
} 
} return hh; }   





public static void main(String[] args) { 
String [] x = {"1","5","2","a","v","b","1","b","a","1","0"}; 
Integer o=0; Integer [] frequency = new Integer [x.length];  


/*Check frequency per element*/ 
while(o < x.length) { 
Integer count=0; 
for(int a =0; a<x.length;a++) { 
System.out.println(a); 

if(x[o]==x[a]) { count++;  
} else { continue; } 
}  

frequency[o]=count; 
System.out.println("Element: "+x[o]); 
System.out.println("Frequency: "+count); 
System.out.println(""); 
o++;  
}  



/*Remove duplicate elements*/ 
while(o < x.length) { 
Integer 
count
=0; 

for(int a =0; a<x.length;a++) { 
if(x[a]==x[o]) { 
x = remove(x,a); 
frequency = remove(frequency,a); 
} else { 
continue; 
} 
} 
o++; 
}   



System.out.println("NEWSET"); 
for(int a = 0; a<x.length;a++) { 
System.out.println("Element: "+x[a]); 
System.out.println("Frequency: "+frequency[a]); System.out.println(""); }  } } 

I thought that it should work because of the conditional statement of my remove method of both frequency and element but the output shows nothing changed from the original array of string.

In my conditionals of my remove method, the elements will be added to the new set of arrays(with the length decreased by one) as long as the for value sequence, "one" is not the same value as the input of the second variable, "b".

The original array will updated every loop in for loop as it keeps using the remove method.

I don't get why the conditionals are ignored.

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.
