2字节数组返回相同的字符串，但不等于

Question

我需要使用ZipOutputStream压缩字节数组，然后检索此数组。之后，原始数组应对应于新数组。 为什么在此代码中2个字节的数组具有相同的值（返回字符串时），但它们不相等：

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
import java.util.zip.ZipOutputStream;

public class Main {
    public static void main( String[] args ) throws IOException {
        byte[] b = "Help me please".getBytes();
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        try( ZipOutputStream zos = new ZipOutputStream( baos ) ) {
            ZipEntry out = new ZipEntry( "1 First" );
            zos.putNextEntry( out );
            zos.write( b, 0, b.length );
            zos.closeEntry();
            zos.close();
        }
        byte[] a = baos.toByteArray();                               //compressed array

        ByteArrayInputStream bais = new ByteArrayInputStream( a );
        try( ZipInputStream zis = new ZipInputStream(bais)) {
            while(zis.getNextEntry() != null ){
                byte[] c = new byte[a.length];
                int length = zis.read( c, 0, c.length );
                System.out.println( "Data: " + new String( c, 0, length));
                System.out.println(c.equals(b));
                zis.closeEntry();
            }
        }
    }
}

输出：

Data: Help me please
false
