     System.out.print (" Enter The mork "); 
     mork = input.nextInt(); 

     if (mork > 90) 
     System.out.print("A"); 

     if (mork1 > 80) 
     System.out.print("B"); 

     if (mork2 > 70) 
      System.out.print("C"); 

     if (mork3 >= 60) 
      System.out.print("D"); 

     else System.out.print("H");

这绝对不是JAVA的JavaScript ...

[编辑]

这里是做一个有效的办法的if/else if/else语句statment在Java，如果这就是你要求的...

import java.util.Scanner; 

public class nothing { 
    public static void main(String[] args) { 
     Scanner input = new Scanner(System.in); 

     int mork; 
     int mork1; // <--- never used... 
     int mork2; // <--- never used... 
     int mork3; // <--- never used... 

     System.out.print(" Enter the mork "); 
     mork = input.nextInt(); 

     if(mork > 90) { 
      System.out.print("A"); 
     }else if(mork > 80) { // <-- changed mork1 to mork since mork1 is never initialized 
      System.out.print("B"); 
     }else if(mork > 70) { // <-- changed mork2 to mork since mork2 is never initialized 
      System.out.print("C"); 
     }else if(mork >= 60) { // <-- changed mork3 to mork since mork3 is never initialized 
      System.out.print("D"); 
     }else{ 
      System.out.print("H"); 
     } 
    } 
}
