    package com.example.android.testing1;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            Button dodo = (Button) findViewById(button1);

            Button dede = (Button) findViewById(button2);

            Button dada = (Button) findViewById(button3);

            Button didi = (Button) findViewById(button4);

            Button hehe = (Button) findViewById(button5);

            return;

        }

        //boolean fafa, soso, raerae, gaga, gege;
        public void main(Button args[]) {
            final boolean fafa = true;
            final boolean soso = true;
            final boolean raerae = true;
            final boolean gaga = true;
            final boolean gege = true;
            boolean returrn;


            OnClickListener list = new OnClickListener() {
                @Override
                public void onClick(View v) {
                    if (fafa == true && soso == true && raerae == true && gaga == true && gege == true) {
                        Toast GetMeToast = Toast.makeText(MainActivity.this, "Open all buttons", Toast.LENGTH_SHORT);
                        GetMeToast.show();

                    }
                }


            };


        }}

I tried to run the code above but was jammed once i clicked the button.

I am new to java. Required some assistance, what i need is that by clicking all the 5 buttons then the toast will appear.

I have tried many way it does not work. I think by creating a Boolean and if method can help me with this.
