MainActivity.java Code:

package com.example.practical_11;
public class MainActivity extends
import AppCompatActivity {
androidx.appcompat.app.AppCompatActivity;
@Override
import android.os.Bundle; protected void onCreate(Bundle
import android.view.View; savedInstanceState) {
import android.widget.Button; super.onCreate(savedInstanceState);
import android.widget.CheckBox;
import android.widget.Toast; setContentView(R.layout.activity_main);
 CheckBox ch1 = (CheckBox) {
findViewById(R.id.ch1); s1 =
CheckBox ch2 = (CheckBox) s1+ch3.getText().toString() +"\n";
findViewById(R.id.ch2); }
CheckBox ch3 = (CheckBox)
findViewById(R.id.ch3); if(ch4.isChecked())
CheckBox ch4 = (CheckBox) {
findViewById(R.id.ch4); s1 =
CheckBox ch5 = (CheckBox) s1+ch4.getText().toString() +"\n";
findViewById(R.id.ch5); }
CheckBox ch6 = (CheckBox)
findViewById(R.id.ch6); if(ch5.isChecked())
Button b1 = (Button) {
findViewById(R.id.b1); s1 =
s1+ch5.getText().toString() +"\n";
b1.setOnClickListener(new }
View.OnClickListener() {
@Override if(ch6.isChecked())
public void onClick(View v) { {
String s1 =""; s1 =
if(ch1.isChecked()) s1+ch6.getText().toString() +"\n";
{ }
s1 =
s1+ch1.getText().toString() +"\n";
} Toast.makeText(getApplicationContext(),
"Selected Subjects"+s1,
if(ch2.isChecked()) Toast.LENGTH_SHORT).show();
{ }
s1 = });
s1+ch2.getText().toString() +"\n";
} }
}
if(ch3.isChecked())

Output:
