Public static void main(String[] args){

char[] ch = {'3 '，' 5 '，' 2 '，' 4 '，' 0 '，' 8 '，' 1 ' }；

int[]toInt = new int[ch . length]；

for(int I = 0； I & ltch. Length; i++){

toInt[I]= integer . parse int(string . value of(ch[I]))；

system . out . print(toInt[I])；

My program is correct, but why is yours wrong? The reason is that int[] a={} Here, the space you allocated to array A is 0, so how can it store 7 numbers? It should be written as follows: int [] a = new int [7]; Or int [] a = new int [ch. length]; Hmm. How interesting ..
