如何將循環值設置為文本字段？

Question

當我在netbeans中使用swing

    Random acak = new Random ();
    int max = 99;
    int []hasilRandom = new int[9];
    for (int i = 0; i <hasilRandom.length; i++){
        hasilRandom[i] = acak.nextInt(max);
        jTextRandom.setText(hasilRandom[i]+", ");
    }

輸出： 48,

我想要的是當我不使用秋千時

    Random acak = new Random ();
    int max = 99;
    int []hasilRandom = new int[9];
    for (int i = 0; i <hasilRandom.length; i++){
        hasilRandom[i] = acak.nextInt(max);
        System.out.print(hasilRandom[i]+", ");
    }

輸出： 48, 30, 98, 78, 70, 16, 40, 2, 7,

對不起，我的語法，我希望大家都明白..：D

Answer 1

嘗試這個：

Random acak = new Random ();
int max = 99;
int []hasilRandom = new int[9];
StringBuilder text = new StringBuilder();
for (int i = 0; i <hasilRandom.length; i++){
    hasilRandom[i] = acak.nextInt(max);
    text.append(hasilRandom[i]+", ");
}
jTextRandom.setText(text.toString());

您每次都覆蓋文本字段中的文本

Answer 2

只需獲取當前文本並像這樣添加它，而不是覆蓋已經存在的內容：

Random acak = new Random ();
int max = 99;
int []hasilRandom = new int[9];
for (int i = 0; i <hasilRandom.length; i++){
    hasilRandom[i] = acak.nextInt(max);
    jTextRandom.setText(jTextRandom.getText() + ", " + hasilRandom[i]); //use getText to append new value to current value
}
