Rewrite existing code with Java 8 Lambda -

i have 1 object, 2 conditions , need convert list.

• selectitem has getlabel , getvalue
• casting problem
• expect result -> list of employees
• object refer class (example: employees.class)

the code looks like:

public static final list<employees> onfilterobjectfromselectitems(final string query,final list<selectitem> selectitemlist) {   final list <employees>result = new arraylist<>();   (selectitem sl : selectitemlist) {     employees x = (employees) sl.getvalue();     if (x.getcode.contains(query) || x.getname.contains(query)) {       result.add(x);     }   }   return result; } 

try following code.

list<employees> employeelist = selectitemlist.stream()     .filter(x-> x.getcode().contains(query) || x.getname().contains(query))     .map(e->(employees)e.getvalue())     .collect(collectors.tolist());
