一个string（） 的问题疑问

String b22= new String(c2, 0, c);
System.out.println(b22);
今天 发现 这样写会 影响下面代码运行 ，也不报错

            System.out.println(new String(c2, 0, c));

这样就没事

什么原理？

会有什么影响，应该都可以啊

看起来没啥毛病~有没有完整点的代码

听君一席话，胜听一席话

从源码上，没有发现任何影响啊

```java
    public String(char value[]) {
        this(value, 0, value.length, null);
    }

    /**
     * Allocates a new {@code String} that contains characters from a subarray
     * of the character array argument. The {@code offset} argument is the
     * index of the first character of the subarray and the {@code count}
     * argument specifies the length of the subarray. The contents of the
     * subarray are copied; subsequent modification of the character array does
     * not affect the newly created string.
     *
     * @param  value
     *         Array that is the source of characters
     *
     * @param  offset
     *         The initial offset
     *
     * @param  count
     *         The length
     *
     * @throws  IndexOutOfBoundsException
     *          If {@code offset} is negative, {@code count} is negative, or
     *          {@code offset} is greater than {@code value.length - count}
     */
    public String(char value[], int offset, int count) {
        this(value, offset, count, rangeCheck(value, offset, count));
    }

```
