int和String的相互转换

public class demo {
    public static void main(String[] args) {
        //int转String
        int number = 100;
        String s = String.valueOf(100);
        System.out.println(s);
        
        System.out.println("-------------");
        
        //String转int
        String t = "100";
        int n = Integer.parseInt(t);
        System.out.println(n);
    }
}
