Minimum value and Index

The java code find a minimum value and its index from array of data
A class Data has defined with two member functions named min and minIndex to find minimum value and its index. A object is created to the class Data with array of integers which are randomly generated from random object. The random generated integer values limited to 1000.
Data are generated from randomly using java Random class


pseudocode of find minimum value

    Read  N integer data  
        

    set  minvaue = MAX 
    
    for n=0 to N-1
 
         check   data[n] < minvalue
               minvalue = data[n]
         
    end for   

    print minvalue

 

pseudocode of find minimum value index

    Read  N integer data  
        
    set mindex  =0
    set  minvaue = MAX 
    
    for n=0 to N-1
 
         check   data[n] < minvalue
               minvalue = data[n]
               mindex = n
         
    end for   

    print mindex
