- This is the second homework given by UpSchool.
- Kotlin
- Create an ArrayList with 5 names.
- Ask the user to enter 3 names, separated by commas.
- Split this entered 3-name String using commas and convert it to a list
- Check if this list is plentiful.
- If it is not empty, add it to the 5-name list you created and print the final version to the console.
val names = arrayListOf("Sinem", "Ali", "Hümeyra", "Cem", "Gizem")- Sort the list by letters first, using the names list above.
- Request 1 name from the user.
- Check if this name is in the names list.
- Search for this name in the list, if any, and print all letters on the console, capitalized and reversed.
data class Student(val name: String, val age: Int, val school: String)
val students = arrayListOf(
Student("Ahmet", 20, "Üniversite A"),
Student("Ayşe", 27, "Üniversite B"),
Student("Mehmet", 22, "Üniversite C"),
Student("Fatma", 28, "Üniversite A"),
Student("Ali", 29, "Üniversite B"),
Student("Feyza", 24, "Üniversite A"),
Student("Berkay", 22, "Üniversite B"),
Student("Caner", 26, "Üniversite A")
)- First, print the name of the student with the oldest and the smallest age and which index he is in on the console.
- Filter the ones whose school value is University A in the list.
- Print the list returned from the filtering process to the console one after the other as those over 25 and under.
data class CoinResponse(val name: String, val coinId: String, val hashingAlgorithm: String, val description: String, val image: String, val currentPrice: Float, val priceChangePercentage24h: Float)
data class CoinUI(val name: String, val coinId: String, val description: String, val image: String)
val coinList = arrayListOf(
CoinResponse(
name = "Bitcoin",
coinId = "BTC",
hashingAlgorithm = "SHA-256",
description = "Bitcoin is a decentralized digital currency, without a central bank or single administrator.",
image = "https://example.com/bitcoin.png",
currentPrice = 34789.21,
priceChangePercentage24h = -2.34
),
CoinResponse(
name = "Ethereum",
coinId = "ETH",
hashingAlgorithm = "Ethash",
description = "Ethereum is an open-source, blockchain-based platform that enables developers to build and deploy smart contracts.",
image = "https://example.com/ethereum.png",
currentPrice = 2110.45,
priceChangePercentage24h = 0.78
),
CoinResponse(
name = "Litecoin",
coinId = "LTC",
hashingAlgorithm = "Scrypt",
description = "Litecoin is a peer-to-peer cryptocurrency that enables instant, near-zero cost payments to anyone in the world.",
image = "https://example.com/litecoin.png",
currentPrice = 129.57,
priceChangePercentage24h = -1.12
),
CoinResponse(
name = "Ripple",
coinId = "XRP",
hashingAlgorithm = null,
description = "Ripple is a digital payment protocol and cryptocurrency that is designed to facilitate fast, low-cost international money transfers.",
image = "https://example.com/ripple.png",
currentPrice = 0.5483,
priceChangePercentage24h = 1.45
)
)- Above is an ArrayList with type CoinResponse.
- Convert this ArrayList to a list of type CoinUI and print it to console.
data class Workers(val name: String, val salary: Double)
val workers = arrayListOf(
Workers("Ahmet Yılmaz", 15000.0),
Workers("Ayşe Kaya", 32000.0),
Workers("Mehmet Demir", 29000.0),
Workers("Fatma Şahin", 18500.0)
)- Give each employee a 35% raise using the workers list above.
- Shuffle the list and sort by salary value from smallest to largest.
- Print the highest and lowest salary areas to the console.
- Calculate the average salary and print it on the console.
