[ANSWERED] java – Inspect from a specific range of an array

Posted on November 14, 2022

Solution 1 :

How about

String[] newArray=new String[3];
//Copy the first three elements into newArray
System.arraycopy(s,0,newArray,0,3);

Solution 2 :

After thinking a bit I figured a solution out without the need of creating new array:

 int INSPECTION_LENGTH=3;
String query="two";

public static boolean b(String[] s,int length,String query){
for(int i=0;i<length;i++){
if(s[i].equals(query)){
return true;
}
}

return false;
}

Solution 3 :

Make a sub-list of List

If using a List such as ArrayList rather than a simple array, you can produce a sub-list that is based on the original but masks away unwanted elements.

Make a List from your array.

List < String > allStrings = new ArrayList<>( Arrays.asList( array ) ) ;

Of, if you want a non-modifiable list, use List.of.

List < String > allStrings = List.of( array ) ; 

Get your sub-list, calling List::subList. We must use annoying zero-based index counting. The first number is inclusively the start. The second number is exclusively the end. So getting elements 1, 2, and 3 but not 4 and more translates as ( 0 , 3 ). I might be tempted to write this as ( 1 - 1 , 4 - 1 ) meaning “ordinal one inclusive to four exclusive, subtracting one for index counting”.

List< String > firstThreeStrings = allStrings.subList( 0 , 3 ) ;  // Using annoying zero-based index counting. First number is inclusive while the second is exclusive.

Be aware that any changes to the original List will show through to the sub-list. We have not created a copy, we have a created second view onto the first list’s content, hiding unwanted elements.

Problem :

I have got a String array:

String[] s={“one”,”two”,”three”,”four”};

Now I want to inspect from first three items of that array and do not want the inspection to include the fourth item.
I am using the following code to inspect:

boolean b = Arrays.asList(s).contains(“two”);

Wondering if there is a solution for this!
