- public class ConvertStringToInt {
- public static void main(String[] args) {
- String str="-14545";
- int total=0;
- boolean m=false;
- for(int i=0;i<str.length();i++){
- if(str.charAt(i)=='-'){
- m=true;
- continue;
- }
- if(str.charAt(i)=='+'){
- continue;

- total=(total*10)+(str.charAt(i)-48);
- }
- if(m){
- total=0-total;
- }
- System.out.println(total);
