Java Learning (v) Java class inheritance

1. Making a document for a tool class

javadoc-d Directory-author-version Arraytool.java

Instance:

classarraydemo{ Public Static voidMain (string[] args) {int[] arr = {23,34,54,65,57,7}; //iterating through an arrayArraytool.printarray (arr); //gets the maximum value in the array       intMax =Arraytool.getmax (arr); System.out.println ("The maximum value in the array is" +max); //gets the index of the element in the array       intindex = Arraytool.getindex (arr,57); System.out.println ("57 index position in the array is" +index); }}

Document type of the Build tool class
javac-d doc-author-version Arraytool.java
/*** Array Manipulation tool class *@authorGreymouster *@versionv1.0*/ Public classarraytool{/*** Private construction methods prohibit external instantiation of objects*/    PrivateArraytool () {}/*** Traversal Array method after traversal for [element 1, Element 2, Element 3,....] *@paramarr to traverse the array*/     Public Static voidPrintArray (int[] arr) {System.out.print ("[");  for(intx=0;x<arr.length;x++){            if(x = = Arr.length-1) {System.out.println (arr[x]+"]"); }Else{System.out.print (arr[x]+","); }         }    }        /*** method to get the maximum value in the array *@paramArr Array *@returnreturns the maximum value in an array*/     Public Static intGetmax (int[] arr) {         //the element that joins the array is the maximum value         intmax = Arr[0];  for(intx=1;x<arr.length;x++){             if(max<Arr[x]) {Max=Arr[x]; }         }                returnMax; }        /*** Get the index of the values in the array *@paramthe values in the ARR array value array *@returnIndex returns the indexed value in the array if there is no return-1. */     Public Static intGetIndex (int[] arr,intvalue) {             intindex =-1;  for(intx=0;x<arr.length;x++){           if(Arr[x] = =value) {Index=x; }       }              returnindex; }}
