已知某分页系统，主存容量为 64K，页面大小为1K ，对一个4页大的作业， 其 0、1、2、3页分别被分配到主存的 2、4、6、7 块中。将十进制的逻辑地址1023、2500、3500、4500转换成物理地址。请用Java语言实现

public class PagingSystem {
    private final int PAGE_SIZE = 1024; // 页面大小为1K
    private final int TOTAL_PAGES = 64; // 主存容量为64K，所以总页数为64
    private final int[] PAGE_TABLE = {2, 4, 6, 7}; // 0,1,2,3页分别被分配到主存的2,4,6,7块中

    // 将逻辑地址转换成物理地址
    public int translate(int logicalAddress) {
        int page = logicalAddress / PAGE_SIZE; // 获取页号
        int offset = logicalAddress % PAGE_SIZE; // 获取页内偏移量

        if (page >= 4) { // 如果页号超出范围，则返回-1表示转换失败
            return -1;
        }

        int frame = PAGE_TABLE[page]; // 获取页表中对应页号的块号
        int physicalAddress = frame * PAGE_SIZE + offset; // 计算物理地址

        return physicalAddress;
    }

    public static void main(String[] args) {
        PagingSystem pagingSystem = new PagingSystem();

        int logicalAddress1 = 1023;
        int physicalAddress1 = pagingSystem.translate(logicalAddress1);
        System.out.println("逻辑地址：" + logicalAddress1 + "，物理地址：" + physicalAddress1);

        int logicalAddress2 = 2500;
        int physicalAddress2 = pagingSystem.translate(logicalAddress2);
        System.out.println("逻辑地址：" + logicalAddress2 + "，物理地址：" + physicalAddress2);

        int logicalAddress3 = 3500;
        int physicalAddress3 = pagingSystem.translate(logicalAddress3);
        System.out.println("逻辑地址：" + logicalAddress3 + "，物理地址：" + physicalAddress3);

        int logicalAddress4 = 4500;
        int physicalAddress4 = pagingSystem.translate(logicalAddress4);
        System.out.println("逻辑地址：" + logicalAddress4 + "，物理地址：" + physicalAddress4);
    }
}
