String，int，Integer之间的转换

public class Test{

    public static void main(String[] args) {
        //int转换成Integer
        Integer in = new Integer(10);
        //Integer转换成int
        int i = in.intValue();
        //String转换成Integer
        Integer in1 = new Integer("10");
        //Integer转换成String
        String s = in1.toString();
        //String转换成int
        int i1 = Integer.parseInt("11");
        int i2 = Integer.parseInt("10",16);
        //int转成String
        String s1 = i1+"";
        String s2 = Integer.toString(i1);
    }
}
