java学习经验总结------单链表的建立与结点的增删


在该链表结点有data数据,并且还有cpu,分给cpu随机的时间片,根据时间片大小进行结点data的排序

链表结点的建立

class LinkNode{//结点的建立
private int data;
private int cpu;
public LinkNode next;
public LinkNode(int data) {
this.data=data;
this.cpu=new Random().nextInt(10) + 1;; }
public int getCpu() {
return cpu;
}
public void setCpu(int cpu) {
this.cpu = cpu;
}
public int getData() {
return data;
}
public void setData(int data) {
this.data = data;
}

链表的构建过程以及添加节点、删除节点

class Linklist{
private LinkNode front;
private LinkNode current;
public Linklist() {
current=front=new LinkNode(0);//单链表头节点必须对象化,否则会导致空指针异常 }
public void add(int data) {//链表的添加
LinkNode Node = new LinkNode(data);
while(current.next!=null) {
current=current.next;
}
current.next=Node;
}
public void print() {//链表的打印
LinkNode node =front.next;
while(node!=null) {
System.out.println(node.getData()+" "+node.getCpu());
node=node.next;
}
System.out.println("======================================");
}
public void sort(int temp) {//对链表进行排序
int a;
int b;
for(int i=0;i<temp-1;i++)
{ LinkNode now=front.next;
for(int j=0;j<temp-i-1;j++) {
if(now.getCpu()>now.next.getCpu()) {
a=now.getData();
b=now.next.getData();
now.setData(b);
now.next.setData(a);
a=now.cpu;
now.cpu=now.next.cpu;
now.next.cpu=a;
System.out.println(); }
now=now.next;
}
} }
public void delete(int num) {//链表的删除
int i=1;
LinkNode node=front;
while(i<num) {
node=node.next;
i++;
} node.next=node.next.next; }
}
