1. block中包含的元素

2. block代码实现

package Block;
// 区块的实现
public class Block {
    private int index;
    private String hash;
    private long timeStamp;
    private String previousHash;
    private String data;
    private long nonce;
    public Block(int index, String hash, long timeStamp, String previousHash, String data, long nonce) {
        this.index = index;
        this.hash = hash;
        this.timeStamp = timeStamp;
        this.previousHash = previousHash;
        this.data = data;
        this.nonce = nonce;
    }
    public int getIndex() {
        return index;
    }
    public void setIndex(int index) {
        this.index = index;
    }
    public String getHash() {
        return hash;
    }
    public void setHash(String hash) {
        this.hash = hash;
    }
    public long getTimeStamp() {
        return timeStamp;
    }
    public void setTimeStamp(long timeStamp) {
        this.timeStamp = timeStamp;
    }
    public String getPreviousHash() {
        return previousHash;
    }
    public void setPreviousHash(String previousHash) {
        this.previousHash = previousHash;
    }
    public String getData() {
        return data;
    }
    public void setData(String data) {
        this.data = data;
    }
    public long getNonce() {
        return nonce;
    }
    public void setNonce(long nonce) {
        this.nonce = nonce;
    }
}
