java - Get lowest sale from week of sales -

My job tells me to get sales for eight weeks, sales of the highest week and the lowest weekly sale though It can not understand how to get the minimum weeks and prices. I am very new to Java

This is my code:

  public static zero main (string [] args) {int totalSales = 0; Int averages = 0; Int highest = 0; Int highest = 0; Int lower cell = 0; Intackware Wake = 0; For (Int i = 0; I    
 
 
  if (lowest  
  If (s & lt; lowest) {min} =; minimize = wiki = i = 1;}   
 I + 1;}
