Using Scanner Class Instead of giving input in the code, using Scanner class in Java, we can read input at runtime itself. So, making use of this for our problem, we read the inputs – number whose log has to be found (n) and the base for log (b). As log is not fixed,it co...

当使用 Scanner 类时,可以从不同的输入源读取数据,包括标准输入流、文件和字符串等。下面是几个使用不同输入源的示例: (1)从标准输入流读取数据 public class Example { public static void main(String[] args) { // 创建 Scanner 对象,使用标准输入流作为输入源 ...
