Hi all, I wanted to create this question/answer on how to convert a string to an integer in Java as this is something that I often get asked a lot about.
@Test public void givenBinaryString_whenParsingInt_shouldConvertToInt() { String givenString = "101010"; int result = Integer.parseInt(givenString, 2); assertThat(result).isEqualTo(42); } Naturally, it’s also possible to use this method with any other radix such as 16 (hexadecimal) or ...
String str = "123"; int num = Integer.parseInt(str); // 正确 2. 处理格式错误 在转换前验证String值的格式。 代码语言:txt 复制 String str = "abc"; try { int num = Integer.parseInt(str); // 这将抛出NumberFormatException } catch (NumberFormatException e) { System....
