Question

java如何删除掉数组中的某个元素？？

比如一个数组：String arrays={"1","2","3","5",“6”};
for(String s:arrays){
if(s.equals("2")){
//移除掉元素2

}

}

Answer 1

String[] arrays={"1","2","3","5","6"};
String[] tempArr = new String[arrays.length];
int i = 0;
for(String s:arrays){
if(!s.equals("2")){
tempArr[i] = s;
i++;
}
}
for(int j = 0; j < tempArr.length; j++) {
System.out.println(tempArr[j]);
}

// 数组本身是不可以移除元素的 但可以通过中间变量来实现数组的移除
