如何在java中清除整个数组？

我需要做一个“清除”按钮来删除屏幕上和阵列中的所有图像。我目前正在使用

EZ.removallezelements（），但这会清除所有内容。甚至标签调色板和背景（画布）。如何从阵列和画布中删除所有放置的图片

这是我的密码

sticker [] arraysticker = new sticker [80];
int image = 0;
int flag = 0;
else if (backgroundPicture.isPointInElement(clickX, clickY) && !savePicture.isPointInElement(clickX, clickY) 
        && !loadPicture.isPointInElement(clickX, clickY) && !clearPicture.isPointInElement(clickX, clickY) 
        && !rectanglePicture.isPointInElement(clickX, clickY)){
    if (flag == 1){ //if hatSoundPlay is true
        sticker sticker1 = new sticker();//creates a new sticker1
        sticker1.sticker11("hat.png", clickX, clickY);//places sticker
        arraysticker[image] = sticker1;//puts sticker 1 into the array
        image ++;//increments image by 1
        hatsound.play(); //and a hatsound will play

然后用
重复3次，如果（flag==2）{
然后是3然后是4。每个标志都是一个新标签

这是我的清晰代码

else if (clearPicture.isPointInElement(clickX, clickY)){
    EZ.removeAllEZElements();
    //make a clear array
    EZ.addImage("background.png", EZ.getWindowWidth() / 2, EZ.getWindowHeight() / 2);
    EZ.addImage("rectangle.png", EZ.getWindowWidth() / 2, EZ.getWindowHeight () / 7);
    EZ.addImage("hat.png",1* EZ.getWindowWidth() / 10, EZ.getWindowHeight () / 6);
    EZ.addImage("blunt.png",1* EZ.getWindowWidth() / 3, EZ.getWindowHeight () / 6);
    EZ.addImage("dealwithit.png",3* EZ.getWindowWidth() / 5, EZ.getWindowHeight () / 6);
    EZ.addImage("weed.png",10* EZ.getWindowWidth() / 11, EZ.getWindowHeight () / 6);
    EZ.addImage("save.png", 19* EZ.getWindowWidth() / 20, 3* EZ.getWindowHeight () / 9);
    EZ.addImage("load.png", 19* EZ.getWindowWidth() / 20, 4* EZ.getWindowHeight () / 9);
    EZ.addImage("clear.png", 19* EZ.getWindowWidth() / 20, 5* EZ.getWindowHeight () / 9);
}

我正在清除所有图像并替换原始图像。问题是，带有坐标的图像仍然存储在数组中。清除需要同时清除画布和数组

这是我的全部代码。只删除EZ.addImage和EZ.addSound代码

        int clickX = EZInteraction.getXMouse(); //get x coordinates
