int i = 10;
double j=1.0;
String str_i=Integer.toString(i);
String str_j = Double.toString(j);

double dd = Double.valueOf("123.2");

int 转化成String：
int i=10;
String str=Integer.toString(i);
double 转化成String：
double d=10.0;
String str=Double.toString(d);
String 转化成double：
String str="123456";
double d=Double.valueOf(str).doubleValue();

不好意思写错了，
double dd = Double.parseDouble("123.2");

[xuxk]

public class trans{

public static void main(String ag[]){
int a = 12;
double b = 122;
String s1 = a + "";
String s2 = b + "";

System.out.println("s1 and s2: "+s1+" "+s2);

String s = "12345";
try{
double d = (new Double(s)).doubleValue();
System.out.println("d: "+d);
}
catch(NumberFormatException e){
System.out.println("s is not a number");
}
}
}

都对阿.糟了,怎么给分啊.我加10分,每个10分吧.
顺便问一下,你们熟悉各种control和Variant, safeArray和我联络
