如何輸入浮點數

Question

public static void main(String[] args) 
    { 

Scanner input = new Scanner(System.in); 



    System.out.println("Enter a floating point number"); 

    float nA= java.util.Scanner.nextFloat(); 
    double nB= Math.pow(a, 3.5); 

System.out.println("nB = nA^3.5" +nB); 

    } 
} 

在此代碼我嘗試允許輸入浮點數nA的，但即時

不知道如何

public static void main(String[] args) 
    { 
     Scanner input = new Scanner(System.in); 



     System.out.println("Enter a floating point number"); 

     float nA= input.nextFloat(); 
     double nB= Math.pow(nA, 3.5); 

     System.out.println("nB = nA^3.5" +nB); 


    }
