When I was working on the project today, I encountered a problem. I need to convert the String type variable to the int type. As usual, I wrote var I = Integer. parseInt ("112"), but
An error occurred while converting String to int.

when I was doing the project today, I encountered a problem that required converting a variable of type string to int. As usual, I wrote var i = Integer.parseint ("112"), but the console error says "' Integer ' is undefined". Later, only to know
Count = integer. parseint (string) all. Get (0 ));
Execution error: Java. Lang. classcastexception: Java. Lang. Integer cannot be cast to Java. Lang. String
Solution: change the statement marked in red to Count = integer. parseint (all. Get (0).
In Java to convert a String type to int, you need to use the parseint () method in the Integer class or The ValueOf () method for conversion.Example 1:
123456
String str = "123";try{ int

Q: How do I parse a string to int?
A: There are three kinds of simple methods:
string source = "1412"; int result = 0; // 使用Convert.ToInt32(string value); result = Convert.ToInt32(source); // 使用Int32.Parse(string value); result =
Count=integer.parseint ((String) all.get (0));
Implementation times error: Java.lang.ClassCastException:java.lang.Integer cannot be cast to java.lang.String
Workaround: Change the red-flagged statement to Count=integer.parseint (all.get (0).

Q: How to resolve a string to an int?
A: There are three simple methods:
String source = "1412 ";
Int result = 0;
// Use convert. toint32 (string value );
Result = convert. toint32 (source );
// Use int32.parse (string value );
Result =
1, int to string
Use tostring
Or convert. tostring () is as follows:
For example:Int varint = 1;String varstring = convert. tostring (varint );String varstring2 = varint. tostring ();
