I don't know kotlin, I had convert the kotlin code in java and paste that code but there is lots of confusion to read that bytecode. can anyone help me, please to convert this code.

please convert this code in java https://github.com/supercoffee/seven-segment-view/blob/master/sevensegmentview.example/src/main/java/com/bendaschel/sevensegmentview/example/MainActivity.kt

package com.bendaschel.sevensegmentview.example

import android.graphics.Color
import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import android.widget.LinearLayout
import com.bendaschel.example.R
import com.bendaschel.sevensegmentview.SevenSegmentView


class MainActivity : AppCompatActivity() {

    private lateinit var sv: SevenSegmentView

    private lateinit var colorPicker: LinearLayout

    private val colors = listOf<Int>(Color.GREEN, Color.BLUE, Color.RED, Color.MAGENTA, Color.YELLOW)

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        sv = findViewById(R.id.display) as SevenSegmentView

        sv.setOnClickListener {
            val next = (sv.currentValue + 1) % 10
            sv.currentValue = next
        }

        colorPicker = findViewById(R.id.color_picker) as LinearLayout
        colors.forEach { color ->
            val button = layoutInflater.inflate(R.layout.color_picker_item, colorPicker, false)
            button.setOnClickListener {
                sv.onColor = color
                sv.offColor = Color.argb(50, Color.red(color), Color.green(color), Color.blue(color))
            }
            button.setBackgroundColor(color)
            colorPicker.addView(button)
        }
    }
}

I have written the basic code, Its upto you to take it to next level. Here you have to implement your onclick listner and for loop

public class temp extends AppCompatActivity {

    SevenSegmentView sv;
    LinearLayout colorPicker;

  Integer[] colors ={Color.GREEN, Color.BLUE, Color.RED, Color.MAGENTA, Color.YELLOW};

);

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        sv = (SevenSegmentView) findViewById(R.id.display);
        colorPicker = (LinearLayout)findViewById(R.id.color_picker);

 sv.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int next = (sv.currentValue + 1) % 10;
                    sv.currentValue = next;
                }
            });
      for (Integer color: colors) {
        Button button = getLayoutInflater().inflate(R.layout.color_picker_item, colorPicker, false);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                sv.onColor = color;
                sv.offColor = Color.argb(50, Color.red(color), Color.green(color), Color.blue(color));
            }
        }); 

        button.setBackgroundColor(color);
        colorPicker.addView(button);

    }
}

            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_main)

            sv = (SevenSegmentView) findViewById(R.id.display);

            sv.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int next = (sv.getCurrentValue() + 1) % 10;
                    sv.setCurrentValue(next);
                }
            });

            colorPicker = findViewById(R.id.color_picker);

            for (Integer color: colors) {
                Button button = getLayoutInflater().inflate(R.layout.color_picker_item, colorPicker, false);
                button.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        sv.setOnColor(color);
                        sv.setOffColor(Color.argb(50, Color.red(color), Color.green(color), Color.blue(color)));
                    }
                });
                button.setBackgroundColor(color);
                colorPicker.addView(button);
            }
        }
    }
