使用bufferedreader读取文件并存储字符串和整数

Question

我想读一个如下所示的txt文件（parameters.txt）：

1 
5
8
wa
wb

这是我的代码来迭代它：

private void storeCacheParams() {
        try {

            BufferedReader reader = new BufferedReader(new FileReader(parameters));
            int cache = reader.read();
            if ( cache == 1 ) {
                cacheType = "direct-mapped";
            } else if ( cache == 2 ){
                cacheType = "2-way set associative";
            }

            offsetBits = reader.read();
            indexBits = reader.read();
            allPol = reader.readLine();
            writePol = reader.readLine();

            System.out.println("Cache: " + cacheType);
            System.out.println("Offset Bits: " + offsetBits);
            System.out.println("Index Bits: " + indexBits);
            System.out.println("Allocation Policy: " + allPol);
            System.out.println("Write Policy: " + writePol);

        } catch (IOException e ) {
            e.printStackTrace();
        }
    }

我将我读取的每一行存储到一个int或String变量中。这是我的变量声明：

private String cacheType;
    private int offsetBits;
    private int indexBits;
    private String allPol;
    private String writePol;

问题在于打印出来：

Cache: 2-way set associative
Offset Bits: 13
Index Bits: 10
Allocation Policy: 5
Write Policy: 8

但偏移位应为5，索引位应为8，allPol应为wa，writePol应为wb。我的程序从哪里获得13和10？
