需要編寫某種方法

Question

所以我有一個作業問題。這是我需要做的：

Write the definition of a method , oddsMatchEvens , whose two parameters  are arrays  of integers  of equal  size. The size of each array  is an even number. The method  returns true  if and only if the even-indexed elements  of the first array  equal  the odd-indexed elements  of the second, in sequence. That is if w is the first array  and q the second array , w[0] equals  q[1], and w[2] equals  q[3], and so on.

我所擁有的是：

public boolean oddsMatchEvens(int[] w, int[] q){ 
int count = 0; 

for(int i=0; i < w.length; i++){ 
if(w[i].equals(q[i + 1])){ 
count++; 
if(count == w.length){ 
return true; 
} 
} 
} 

我收到此錯誤：

⇒     You almost certainly should be using: && 
     ⇒     You almost certainly should be using: += 
     ⇒     You almost certainly should be using: >= 

Answer 1

試試這個：

if(w[i] == q[i + 1]) 

「等於」方法用於對象。

當然一個布爾值必須總是返回。

方法的工作版本：

public boolean oddsMatchEvens(int[] w, int[] q) { 
    int count = 0; 
    for (int i = 0; i < w.length; i++) { 
     if (w[i] == q[i + 1]) { 
      count++; 
      if (count == w.length) { 
       return true; 
      } 
     } 
    } 

    return false; 
} 

Answer 2

public boolean oddsMatchEvens(int[] w, int[] q){ 
    int count = 0; 

    for(int i=0; w.length >= i; i++){ 
     count += 1; 
     if(w[i] == q[i + 1] && count == w.length){ 
      return true; 
     } 
    } 
} 

Answer 3

你應該把外面的回報循環。

for(int i=0; i < w.length; i++){.....} 
return count==w.length;
