Java数组元素比较与合并操作示例

public ArrayList compare(String[] array1,String[] array2) {
        ArrayList array = new ArrayList();

       int array1long =0;
       int array2long =0;
       if(array1Size>array2Size){
           size = array2Size;
           array1long = array1Size-array2Size;
       }else{
           size = array1Size;
           array2long = array2Size-array1Size;
       }
       for(int i=0;i<size;i++){
           if(!array1[i].equals(array2[i])){
               array.add(array1[i]);
               array.add(array2[i]);
           }
       }
       if(array1long!=0){
