+===== Sample Problem Scenario =====
+//Here we have one example for this problem(it can be occurred in while or for condition as well://
+<code Java>
+public class test {static int y=0;
+	 public static void find2(Integer x) {
+		  if (y>=y){
+		    x=0;
+		  }
+		}
+}
+</Code>
+===== Sample Counter Scenario =====
+<code Java>
