Java 如何使用if-else语句调用方法

正如标题所说：我有一个方法需要调用，但我不确定如何调用。方法如下：

public static int wordOrder(int order, String result1, String result2){
    order = result1.compareToIgnoreCase(result2);
    if (order == 0){
        System.out.println("The words are the same.");
    }else if (order > 0){
        System.out.println("The order of the words alphabetically is " +result2+ " then " +result1+ ".");
    }else{
        System.out.println("The order of the words alphabetically is " +result1+ " then " +result2+  ".");
    } 
    return order;
  }

---

在main方法中，我该怎么称呼它呢？任何帮助都会很好！谢谢

像这样：

wordOrder（1，“a”，“b”）

（第一个参数毫无意义）。

如下：

wordOrder（1，“a”，“b”）（尽管第一个参数没有意义）。
它应该是这样的

public static void main(String [] args){
   int myOrder = wordOrder(1, "One word", "Second word");
}

public static int wordOrder(int order, String result1, String result2){
    order = result1.compareToIgnoreCase(result2);
    if (order == 0){
        System.out.println("The words are the same.");
    }else if (order > 0){
        System.out.println("The order of the words alphabetically is " +result2+ " then " +result1+ ".");
    }else{
        System.out.println("The order of the words alphabetically is " +result1+ " then " +result2+  ".");
    } 
    return order;
  }

主要方法

 public static void main(String[] args) {
       int resultFromMethod= wordOrder(2,"result1","result2");
    // your method accept argument as int, String , String and 
    // it is returning int value
    }

这是你的方法

    public static int wordOrder(int order, String result1, String result2){
        order = result1.compareToIgnoreCase(result2);
        if (order == 0){
            System.out.println("The words are the same.");
        }else if (order > 0){
            System.out.println("The order of the words alphabetically is " +result2+ " then " +result1+ ".");
        }else{
            System.out.println("The order of the words alphabetically is " +result1+ " then " +result2+  ".");
        }
        return order;
    }

qqilihq给了您正确的答案，但您可以从函数中删除未使用的变量并生成函数：

public static int wordOrder(String result1, String result2){
  int order = result1.compareToIgnoreCase(result2);
  if (order == 0){
    System.out.println("The words are the same.");
  }else if (order > 0){
    System.out.println("The order of the words alphabetically is " +result2+ " then " +result1+ ".");
  }else{
    System.out.println("The order of the words alphabetically is " +result1+ " then " +result2+  ".");
  } 
  return order;
}

wordOrder("a","b");

并调用此函数：

public static int wordOrder(String result1, String result2){
  int order = result1.compareToIgnoreCase(result2);
  if (order == 0){
    System.out.println("The words are the same.");
  }else if (order > 0){
    System.out.println("The order of the words alphabetically is " +result2+ " then " +result1+ ".");
  }else{
    System.out.println("The order of the words alphabetically is " +result1+ " then " +result2+  ".");
  } 
  return order;
}

wordOrder("a","b");

public static int wordOrder(String result1, String result2){
  int order = result1.compareToIgnoreCase(result2);

  }else{
    System.out.println("The order of the words alphabetically is " +result1+ " then " +result2+  ".");
  } 
  return order;
}

wordOrder("a","b");

并调用此函数：

public static int wordOrder(String result1, String result2){
  int order = result1.compareToIgnoreCase(result2);
  if (order == 0){
    System.out.println("The words are the same.");
  }else if (order > 0){
    System.out.println("The order of the words alphabetically is " +result2+ " then " +result1+ ".");
  }else{
    System.out.println("The order of the words alphabetically is " +result1+ " then " +result2+  ".");
  } 
  return order;
}

wordOrder("a","b");

如果我理解，您只想从主方法调用一个方法。代码可能是这样的

public static void main(String [] args){
   int myOrder = wordOrder(1, "One word", "Second word");
}

public static int wordOrder(int order, String result1, String result2){
    order = result1.compareToIgnoreCase(result2);
    if (order == 0){
        System.out.println("The words are the same.");
    }else if (order > 0){
        System.out.println("The order of the words alphabetically is " +result2+ " then " +result1+ ".");
    }else{
        System.out.println("The order of the words alphabetically is " +result1+ " then " +result2+  ".");
    } 
    return order;
  }

另请注意：只有当方法
wordOrder
设置为静态时，才能执行此操作，否则将显示无法从静态上下文引用非静态方法。

如何设置参数？只需像给定示例中那样编写参数。@Salma与调用所有其他方法相同
System.out.println（String s）
