[JAVA] Screen transition using Intent in Kotlin

About screen transition using Intent in android studio Kotlin

It's been a while since I started learning Kotlin, so I wondered how to write code that I used to write in Java in Kotlin, so I briefly wrote screen transitions using Intent.

There was a slightly different notation from Java, so I've summarized it this time.

Java

Intent intent = Intent(MainActivity.this, SecondActivity.class)
startActivity(intent)

This was a screen transition using Intent in Java, so in Kotlin,

Kotlin

val intent: Intent = Intent(MainActivity.this, SecondActivity.class)
startActivity(intent)

When I thought that I could go with this, I got an error

After investigating various things,

Kotlin

val intent = Intent(this, SecondActivity::class.java)
startActivity(intent)

This person was able to make a screen transition. It seems that it was simply written incorrectly,

::class.java

 The part did not come with a bad pin ...

class.java

 I think that part means that it's a Java class, but ...

 I will add it as soon as I understand it.
