每当我运行我的代码时,它都会返回此错误消息:
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 5
at java.lang.String.charAt(Unknown Source)
at codes.Main.main(Main.java:10)
这是我的代码:
package codes;
public class Main {
public static void main(String[] args) {
String cord1 = "Name: x=23 y=60 z= 600";
String cord2 = "Name: x=200 y=20 z= 300";
int c1 = cord1.length();
String mychar = String.valueOf("cord1".charAt(0));
for (int a = 0; a < c1; a++){
mychar = String.valueOf("cord1".charAt(a));
if (mychar == ":"){
break;
}else{
cord1.substring(a);
}
}
}
}
