绝对值，平方根，对数，正弦值分别对应Math中Math.abs(),Math.sqrt(),Math.log(),Math.sin();
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scanner=new Scanner(System.in);
double num = scanner.nextDouble();
//write your code here......
System.out.println(Math.abs(num));
System.out.println(Math.sqrt(num));
System.out.println(Math.log(num));
System.out.println(Math.sin(num));
}
}
