How would I go about turning JavaScript into Java? [closed]

I would like to use the following code in Android studio, instead of via a web browser. However, I am having trouble converting javascript into java. Particularly the first variable that defines several other variables below. I would appreciate assistance. This is the beginning of an idle game.

main.js

 var gameData = {
        Points: 0,
        PointsPerClick: 1,
        PointsPerClickCost: 10
      }
    
      const perClickUpgrade = document.getElementById("perClickUpgrade"); 
    
      perClickUpgrade.addEventListener("click", function handleClick() { 
      
      perClickUpgrade.textContent = "Upgrade Evolution Level (Currently Level " + gameData.PointsPerClick + ") Cost: " + gameData.PointsPerClickCost + " Points";
      
      }); 
    
      function Upgrade() {
        gameData.Points += gameData.PointsPerClick
        document.getElementById("EvolPoints").innerHTML = gameData.Points + " Evolution Points"
    
      }
    
      function BuyPointsPerClick() {
        if (gameData.Points >= gameData.PointsPerClickCost) {
          gameData.Points-= gameData.PointsPerClickCost
          gameData.PointsPerClick += 1
          gameData.PointsPerClickCost *= 2
          document.getElementById("EvolPoints").innerHTML = gameData.Points + " Evolution Points"
        document.getElementById("perClickUpgrade").innerHTML = "Upgrade Evol Level (Currently Level " + gameData.PointsPerClick + ") Cost: " + gameData.PointsPerClickCost + " Points"
        }
    
    
        var mainGameLoop = window.setInterval(function() {
          Upgrade()
        }, 1000)
      
    function LevelTen() {
    if (gameData.Points >= 10 ) {
      alert("This is an alert message box.");  // display string message
    }
    
    }
    
      }
      function LevelTen() {
        if (gameData.PointsPerClick > 9 && gameData.PointsPerClick < 11) {
          alert("Your Creature Has Evolved to Level Ten!");  // display string message      
        }
        }

Answer

Particularly the first variable that defines several other variables below. I would appreciate assistance.

One solution is to create a class named GameData with publicly accessible static variables:

class GameData {
    public static int points = 0;
    public static int pointsPerClick = 1;
    public static int PointsPerClickCost = 10;
}

Now you can access these variables using the dot notation: GameData.points.

However, I should specify that this is not idiomatic Java. An idiomatic solution would create a class named GameData and then instantiate objects of that class using the new keyword.
