java - Looping javaBean atributes -

i have java bean

public class bean {  private object field1; private object field2;  public object getfield1() {     return field1; }  public void setfield1(object field1) {     this.field1 = field1; }  public object getfield2() {     return field2; }  public void setfield2(object field2) {     this.field2 = field2; } } 

i want set fields i'm doing hardcoded

bean c1 = new bean();  c1.setfield1(hmap.get(headers[1])); c1.setfield2(hmap.get(headers[2])); 

i cycle because have 17 fields.

for (count = 1; count < headers.length; count++) { c1.setfield1,2,3...("parameter_" + count, messages.getstring("field." + headers[count]));} 

how can implement this? using jdk 16

using reflection, follows:

    bean c1 = new bean();      c1.setfield1("object 1");     c1.setfield2("object 2");      (int count = 1; count < headers.length; count++)      {         //concatenate method name         string methodname = "getfield" + count;          // using reflection, collection of methods in bean class         method[] methods = bean.class.getmethods();          for(method method : methods)         {             if (method.getname().equals(methodname))             {                 // if it's method want, invoke using                  // required params                 method.invoke("parameter_" + count, messages.getstring("field." + headers[count]));             }         }     }
