Answer 1

This worked for me:

   Espresso.onView(ViewMatchers.withId(R.id.radiobutton)).check(ViewAssertions.matches(isChecked()))

Answer 2

        if(jRadioButton1.isSelected()){
            jTextField1.setText("Welcome");
        }
        else if(jRadioButton2.isSelected()){
            jTextField1.setText("Hello");
        }

You can also maintain a flag value based on listener,

 radioButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            public void onCheckedChanged(CompoundButton arg0, boolean arg1) {

                //handle the boolean flag here. 
                  if(arg1==true)
                         //Do something

                else 
                    //do something else

            }
        });

Or simply isChecked() can also be used to check the state of your RadioButton.

Here is a link to a sample,

And then based on the flag you can execute your function.

Simple Solution

radioSection.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
          @Override
          public void onCheckedChanged(RadioGroup group1, int checkedId1) {
              switch (checkedId1) {
                  case R.id.rbSr://radiobuttonID
                      //do what you want
                      break;
                  case R.id.rbJr://radiobuttonID
                      //do what you want
                      break;
              }
          }
      });
