java 数据类型的转换
1,整型-->符串型:
int n=100;
String str="";
str = Integer.toString(n);
2,数字转换成字符串:
String str="";
str = String.valueOf(num); //num为任意数字型
3,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 );
