如何在Java中替换数组元素？

Question

我有这个数组：

array = [null, p, ;, z,null, OR, y] 

我想用任何其他值替换null值。我该怎么做？

Answer 1

for (pos=0;pos<array.length;pos++) {
    if(array[pos]==null) {
       array[pos]=xyz
    }
}

Answer 2

喜欢这个

String[] values= {null,"p", ";","z",null, "OR","y"};        
List<String> list=new ArrayList<String>(Arrays.asList(values));
Collections.replaceAll(list, null, "newVal");
values = list.toArray(new String[list.size()]);
System.out.println(Arrays.toString(values));
