Use BeanUtils for Setting setter value

Question

I try to set value using setter but null comes.Please help me with this and give if some other better way is there to do.

import org.apache.commons.beanutils.BeanUtils;

public class TestSetter {

    public static void main(String args[]) throws Exception
    {
        Test t = new Test();
        BeanUtils.setProperty(t,"te","teval");
        System.out.println("tevalue :"+t.getTe());
    }
}
class Test
{
    String te;

    public String getTe() {
        return te;
    }

    public void setTe(String te) {
        this.te = te;
    }

}

Exception :

Exception in thread "main" java.lang.reflect.InvocationTargetException: Cannot set te
    at org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java:1025)

Solution 1

Your class Test should be a public class , Move Test to a own file, make it public and rerun your code.

Solution 2

Set it to the name of the field:

BeanUtils.setProperty(t,"te","teval");

already tried that and it gives this exception Caused by: java.lang.NoSuchMethodException: Property 'te' has no setter method

I accept and tested but now it gives this error.I updated Question .Pls check.

Thank you it works problem is with its missing public modifier.

The test class is not public. BeanUtils doesn't seem capable of parsing protected classes...(ps Otherwise it's right)

@sunleo The test class is not public, see Jayamohan's answer, then apply Shawn and Pradeep's answers
