title: interface abstract methods do not specify a body
body: <p>im tring to make an interface that would serve as a short cut for System.out.print(); but when i compile i get <code>abstract methods do not specify a body</code> and i have no clue what this means</p>
  
  <pre><code>public interface Printing{   
      public  abstract void prt(String print,boolean line){ 
          if(line=true) {   
              System.out.println(print);
          }       
      }   
  
      public abstract void prt(String print){          
          System.out.print(print);       
      } 
  }
  </code></pre>
