To convert an int (primitive integer) value into a String, we can use either String.valueOf() or Integer.toString() method. Internally, the former calls the latter, so Integer.toString() should be preferred. This Java tutorial discusses the following techniques for converting an int to a ...
Java Convert String & Int To convert a int to string: int num = 123; String str = String.valueOf(num); To convert a string to int: String str = "123"; int num = Integer.valueOf(str); 版权声明:本文为博主原创文章,未经博主允许不得转载。
第二种方法:s=String.valueOf(i); //直接使用String类的静态方法,只产生一个对象 第一种方法:i=Integer.parseInt(s);//直接使用静态方法,不会产生多余的对象,但会抛出异常 第二种方法:i=Integer.valueOf(s).intValue();//Integer.valueOf(s) 相当于 new Integer(Integer.parseInt(s)),也会抛异常,但会...
int num1 = 10; double num2 = (double) num1; // 将整数转换为浮点数 复制代码 使用数据类型的转换方法进行转换: String str = "123"; int num = Integer.parseInt(str); // 将字符串转换为整数 复制代码 使用包装类进行转换: Integer num1 = new Integer(10); int num2 = num1.intValue()...
类比C#中的Convert.ToInt32()方法，Integer.parseInt()同样支持额外参数，用于指定转换的数字进制。例如：这段代码将字符串"11"转换为二进制数3。综上，想要在Java中实现与C#中Convert.ToInt32()方法类似的功能，只需采用Integer.parseInt()方法并适当处理可能出现的异常即可。

The Long.parseLong() method in Java is a convenient way to convert a string representation of a number into a long data type. It parses the provided string and returns the equivalent long value. This method is particularly useful when you have an int value that you want to convert to a...
