public static void main(String args[]){ //String with negative sign String str=”-234″; //An int variable int inum = 110; /* Convert String to int in Java using valueOf() method * the value of variable inum2 would be negative after * conversion */ int inum2 = Integer.valueOf(s...
代码的简要介绍: 介绍如何将Java中的字符串转换为整型int)类型。 要将Java中的字符串转换为整型(int)类型,可以使用Integer.parseInt()方法。下面是一个示例代码,展示了如何实现这一转换。 java // StringToIntConversion.java public class StringToIntConversion { public static void main(String[] args) { Strin...
public class JavaStringToIntExample { public static void main (String[] args) { // String s = "fred"; // use this if you want to test the exception below String s = "100"; try { // the String to int conversion happens here int i = Integer.parseInt(s.trim()); // print out ...
If no valid conversion could be performed, a zero value is returned. Note: Only the space character ’’ is considered as whitespace character. Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. If the ...
String str = Double.toString(i); long to String : String str = Long.toString(l); float to String : String str = Float.toString(f); String to integer : str = "25"; int i = Integer.valueOf(str).intValue(); or int i = Integer.parseInt(str); ...

There are a few simple ways to tackle this basic conversion. 2. Integer.parseInt() One of the main solutions is to use Integer‘s dedicated static method: parseInt(), which returns a primitive int value: @Test public void givenString_whenParsingInt_shouldConvertToInt() { String givenString...
