JAVA实现将以下字符串Filesystem Size Used Avail Use% Mounted on devtmpfs 926M 0 926M 0% /dev tmpfs 944M 0 944M 0% /dev/shm tmpfs 944M 440K 944M 1% /run tmpfs 944M 0 944M 0% /sys/fs/cgroup /dev/vda1 40G 2.9G 35G 8% / tmpfs 189M 0 189M 0% /run/user/0 根据换行及回车转换为转换为List<SysFile>对象，跳过第一行标题

好的，以下是 JAVA 实现将该字符串转换为 List<SysFile> 对象的代码：

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        String input = "Filesystem\tSize\tUsed\tAvail\tUse%\tMounted on\n" +
                "devtmpfs\t926M\t0\t926M\t0%\t/dev\n" +
                "tmpfs\t944M\t0\t944M\t0%\t/dev/shm\n" +
                "tmpfs\t944M\t440K\t944M\t1%\t/run\n" +
                "tmpfs\t944M\t0\t944M\t0%\t/sys/fs/cgroup\n" +
                "/dev/vda1\t40G\t2.9G\t35G\t8%\t/\n" +
                "tmpfs\t189M\t0\t189M\t0%\t/run/user/0\n";

        List<SysFile> sysFiles = new ArrayList<>();
        try (Scanner scanner = new Scanner(input)) {
            // 跳过第一行
            if (scanner.hasNextLine()) {
                scanner.nextLine();
            }

            while (scanner.hasNextLine()) {
                String line = scanner.nextLine();
                String[] fields = line.split("\\s+");
                SysFile sysFile = new SysFile();
                sysFile.setFilesystem(fields[0]);
                sysFile.setSize(fields[1]);
                sysFile.setUsed(fields[2]);
                sysFile.setAvail(fields[3]);
                sysFile.setUsePercentage(fields[4]);
                sysFile.setMountedOn(fields[5]);
                sysFiles.add(sysFile);
            }
        }

        System.out.println(sysFiles);
    }
}

class SysFile {
    private String filesystem;
    private String size;
    private String used;
    private String avail;
    private String usePercentage;
    private String mountedOn;

    public String getFilesystem() {
        return filesystem;
    }

    public void setFilesystem(String filesystem) {
        this.filesystem = filesystem;
    }

    public String getSize() {
        return size;
    }

    public void setSize(String size) {
        this.size = size;
    }

    public String getUsed() {
        return used;
    }

    public void setUsed(String used) {
        this.used = used;
    }

    public String getAvail() {
        return avail;
    }

    public void setAvail(String avail) {
        this.avail = avail;
    }

    public String getUsePercentage() {
        return usePercentage;
    }

    public void setUsePercentage(String usePercentage) {
        this.usePercentage = usePercentage;
    }

    public String getMountedOn() {
        return mountedOn;
    }

    public void setMountedOn(String mountedOn) {
        this.mountedOn = mountedOn;
    }

    @Override
    public String toString() {
        return "SysFile{" +
                "filesystem='" + filesystem + '\'' +
                ", size='" + size + '\'' +
                ", used='" + used + '\'' +
                ", avail='" + avail + '\'' +
                ", usePercentage='" + usePercentage + '\'' +
                ", mountedOn='" + mountedOn + '\'' +
                '}';
    }
}

输出结果为：

[SysFile{filesystem='devtmpfs', size='926M', used='0', avail='926M', usePercentage='0%', mountedOn='/dev'}, SysFile{filesystem='tmpfs', size='944M', used='0', avail='944M', usePercentage='0%', mountedOn='/dev/shm'}, SysFile{filesystem='tmpfs', size='944M', used='440K', avail='944M', usePercentage='1%', mountedOn='/run'}, SysFile{filesystem='tmpfs', size='944M', used='0', avail='944M', usePercentage='0%', mountedOn='/sys/fs/cgroup'}, SysFile{filesystem='/dev/vda1', size='40G', used='2.9G', avail='35G', usePercentage='8%', mountedOn='/'}, SysFile{filesystem='tmpfs', size='189M', used='0', avail='189M', usePercentage='0%', mountedOn='/run/user/0'}]
