  • java:字符串与数字的转换

    各种数字类型转换成字符串型

    int i =8;
    String s =Integer.toString(i);//
    String g =String.valueOf(i); // 其中 value 为任意一种数字类型。

    字符串型转换成各种数字类型:

    String s = "169";
    byte b = Byte.parseByte( s );
    short t = Short.parseShort( s );
    int i = Integer.parseInt( s );
    long l = Long.parseLong( s );
    Float f = Float.parseFloat( s );
    Double d = Double.parseDouble( s );

    数字类型与数字类对象之间的转换:

    byte b = 169;
    Byte bo = new Byte( b );
    b = bo.byteValue();

    short t = 169;
    Short to = new Short( t );
    t = to.shortValue();

    int i = 169;
    Integer io = new Integer( i );
    i = io.intValue();

    long l = 169;
    Long lo = new Long( l );
    l = lo.longValue();

    float f = 169f;
    Float fo = new Float( f );
    f = fo.floatValue();

    double d = 169f;
    Double dObj = new Double( d );
    d = dObj.doubleValue();
