🎯定义person类:
🎆类属性:
String name; String sex; LocalDate brithday; boolean remove = false;
🎆有参和无参构造:
public person() { super(); } public person(String name, String sex, LocalDate brithday) { super(); this.name = name; this.sex = sex; this.brithday = brithday; }
🎆 tostring函数的重写:
@Override public String toString() { return "[name=" + name + ", sex=" + sex + ", brithday=" + brithday + "]\n"; }
🎆 get和set函数:
public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public LocalDate getBrithday() { return brithday; } public void setBrithday(LocalDate brithday) { this.brithday = brithday; }
🎆总:
class person { String name; String sex; LocalDate brithday; boolean remove = false; public person() { super(); } public person(String name, String sex, LocalDate brithday) { super(); this.name = name; this.sex = sex; this.brithday = brithday; } @Override public String toString() { return "[name=" + name + ", sex=" + sex + ", brithday=" + brithday + "]\n"; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public LocalDate getBrithday() { return brithday; } public void setBrithday(LocalDate brithday) { this.brithday = brithday; } }
🎯 添加人物函数:
public static void add(Vector<person> v) { System.out.println("添加人物及属性"); System.out.println("请输入添加人物的姓名:"); String n = scan.next(); System.out.println("请输入添加人物的性别:"); String s = scan.next(); System.out.println("请输入添加人物的出生日期(格式:年 月 日)"); int y = scan.nextInt(); int m = scan.nextInt(); int d = scan.nextInt(); v.add(new person(n, s, LocalDate.of(y, m, d))); System.out.println("添加成功"); }
🎯 删除人物函数:
public static void del(Vector<person> v) { System.out.println("请输入删除人物的姓名:"); B: for (;;) { String n1 = scan.next(); int i; for (i = 0; i < v.size(); i++) { if (v.get(i).getName().equals(n1) && v.get(i).remove == false) { v.get(i).remove = true; System.out.println("删除成功!"); if (i == v.size() - 1) break B; } } if (i >= v.size()) System.out.println("未找到该人物!请重新输入:"); } }
🎯 查找人物函数:
public static void find(Vector<person> v) { System.out.println("请输入要查找人物的姓名:"); C: for (;;) { String n2 = scan.next(); int i1; for (i1 = 0; i1 < v.size(); i1++) { if (v.get(i1).getName().equals(n2) && v.get(i1).remove == false) { System.out.println("查找成功!该人物的相关属性为:" + v.get(i1)); if (i1 == v.size() - 1) break C; } } if (i1 >= v.size()) System.out.println("查找失败!请重新输入:"); } }
🎯 修改人物属性函数:
public static void chage(Vector<person> v) { System.out.println("请输入您要修改的人物的姓名:"); D: for (;;) { String n3 = scan.next(); int i2; for (i2 = 0; i2 < v.size(); i2++) { if (v.get(i2).getName().equals(n3) && v.get(i2).remove == false) { System.out.println("该用户存在,下面进入修改操作:"); System.out.println("请输入修改后人物的姓名:"); String n0 = scan.next(); System.out.println("请输入修改后人物的性别:"); String s0 = scan.next(); System.out.println("请输入修改后人物的出生日期(格式:年 月 日)"); int y0 = scan.nextInt(); int m0 = scan.nextInt(); int d0 = scan.nextInt(); v.get(i2).setName(n0); v.get(i2).setSex(s0); v.get(i2).setBrithday(LocalDate.of(y0, m0, d0)); System.out.println("恭喜你修改成功!!修改后的人物及其属性为:"); System.out.println(v.get(i2)); break D; } } if (i2 >= v.size()) { System.out.println("该人物不存在!请重新输入:"); } } }
🎯输出人物属性函数:
public static void put(Vector<person> v) { int i3; for (i3 = 0; i3 < v.size(); i3++) { if ( v.get(i3).remove == false) System.out.println(v.get(i3)); } }
