Question

这是我的代码的一小段。它运行正常，但如果我想为每个String变量str添加一个数字，该怎么办？我该怎么做？请帮忙。 Collections.shuffle（arrlist）;

for(int i=0;i<nb;i++){
    String str = (String) arrlist.get(i);
     //worker.parseXHtml(writer, document, new StringReader("<br>")); 
     worker.parseXHtml(writer, document, new StringReader(str));   
}

尝试

String str = (String) arrlist.get(i)+String.valueOf(someNumber);

如果您想添加i

String str = (String) arrlist.get(i)+String.valueOf(i);

public static void main(String[] args) {
        List arrlist = new ArrayList<>();
        arrlist.add("tester");
        int i = 0;
        String str = (String) arrlist.get(i) + String.valueOf(i);
        System.out.println(str);

    }
