When a double is cast to a long, the result will remain the same, excluding the decimal point. 3. Using Double.longValue Now, let’s explore Double’s built-in method longValue to convert a double to a long: Assert.assertEquals(9999, Double.valueOf(9999.999).longValue()); As we can...
Example 1: Java Program to Convert double to string using valueOf() class Main { public static void main(String[] args) { // create double variable double num1 = 36.33; double num2 = 99.99; // convert double to string // using valueOf() String str1 = String.valueOf(num1); ...
1.Convert.ToInt是数据类型转换成int类型 2. 有三种方法toint16,toint32,toint64 int16-数值范围:-32768 到 32767 int32-数值范围:-2,147,483,648 到 2,147,483,647 int64-数值范围:-9223372036854775808 到 9223372036854775808 3.所以,按需使用吧
In the above example, we have used the parseInt() method of the Integer class to convert the string variables into the int. Here, Integer is a wrapper class in Java. To learn more, visit the Java Wrapper Class. Note: The string variables should represent the int values. Otherwise the co...
