static void winterfell(String[] pyke) { for (int i = 0; i < pyke.length; i += 3){ StringBuilder harrenhal = new StringBuilder(); for (int j = i; j < i + 3; j++) { harrenhal.append(pyke[j] == null ? j + 1 : pyke[j]); harrenhal.append(" "); } System.out.println(harrenhal); } 表示什么 }

这段代码定义了一个名为"winterfell"的静态方法,该方法接受一个字符串数组"pyke"作为参数。在方法中,使用两个for循环,第一个for循环变量"pyke"数组中的每个元素,每次遍历3个元素,第二个for循环将遍历的3个元素拼接成一个字符串,并在每个元素之间添加两个空格,最后将拼接好的字符串输出至控制台。这段代码的输出结果是将"pyke"数组中的元素按每3个一行的格式输出。

vue3的elementplus 穿梭框实现镶嵌表格穿梭组件
可以使用Element Plus的Transfer组件结合Table组件来实现镶嵌表格穿梭组件。具体步骤如下:
1. 引入Transfer和Table组件
```javascript
import { Transfer, TableColumn } from 'element-plus';
```
2. 定义需要穿梭的数据和列配置
```javascript
// 穿梭框左侧表格数据
const tableData = [
{
id: 1,
name: 'John Brown',
age: 18,
address: 'New York No.1 Lake Park'
},
{
id: 2,
name: 'Jim Green',
age: 24,
address: 'London No.1 Lake Park'
},
{
id: 3,
name: 'Joe Black',
age: 30,
address: 'Sydney No.1 Lake Park'
},
{
id: 4,
name: 'Jon Snow',
age: 26,
address: 'Winterfell No.1 Castle'
}
];
// 穿梭框左侧表格列配置
const tableColumns = [
{
label: '姓名',
prop: 'name'
},
{
label: '年龄',
prop: 'age'
},
{
label: '地址',
prop: 'address'
}
];
```
3. 在模板中使用Transfer和Table组件
```html
<el-transfer
v-model="selectedData"
:data="tableData"
:titles="['可选数据', '已选数据']"
>
<el-table-column label="姓名" prop="name"></el-table-column>
<el-table-column label="年龄" prop="age"></el-table-column>
<el-table-column label="地址" prop="address"></el-table-column>
</el-transfer>
```
4. 完整示例代码
```html
<template>
<div>
<el-transfer
v-model="selectedData"
:data="tableData"
:titles="['可选数据', '已选数据']"
>
<el-table-column label="姓名" prop="name"></el-table-column>
<el-table-column label="年龄" prop="age"></el-table-column>
<el-table-column label="地址" prop="address"></el-table-column>
</el-transfer>
</div>
</template>
<script>
import { Transfer, TableColumn } from 'element-plus';
export default {
components: {
Transfer,
TableColumn
},
data() {
return {
tableData: [
{
id: 1,
name: 'John Brown',
age: 18,
address: 'New York No.1 Lake Park'
},
{
id: 2,
name: 'Jim Green',
age: 24,
address: 'London No.1 Lake Park'
},
{
id: 3,
name: 'Joe Black',
age: 30,
address: 'Sydney No.1 Lake Park'
},
{
id: 4,
name: 'Jon Snow',
age: 26,
address: 'Winterfell No.1 Castle'
}
],
selectedData: []
};
}
};
</script>
```
