================int换String 练习一=====================
public class Menu {
public static void main(String[] args) {
int nubber =100;
String s1 = 100+"";
System.out.println("s1= "+s1);
String s2 = String.valueOf(nubber);
System.out.println("s2= "+s2);
String s3 = Integer.toString(nubber);
System.out.println("s3= "+s3);
Integer in = new Integer(nubber);
String s4 = in.toString();
System.out.println("s4= "+s4);
}
}
结果：
s1= 100
s2= 100
s3= 100
s4= 100
=====================String转int 练习二====================
public class Menu {
public static void main(String[] args) {
String s1 = "100";
Integer i = new Integer(s1);
int number1 = i.intValue();
System.out.println("number1=" +number1);
int number2 =Integer.parseInt(s1);
System.out.println("number2=" +number2);
}
}
结果：
number1=100
number2=100
