我不能執行最後一條if語句,我不明白爲什麼。有人能幫助我如何弄清楚嗎?我想讓程序打印在MetodiD.uniformaContenuto()中返回的數組,但是我無法從這段代碼中得到任何東西。不能在這個if-else語句中輸入
這裏的其他類:
public class MetodiD{
public static char[] occorrenzeContenuto(char par[], int a, char b){
int contatore = 0;
for(int i = 0; i < par.length; i++){
if(par[i] != b){
contatore++;
}else{
}
}
if(contatore > a){
for(int k = 0; k < par.length; k++){
if(par[k] != b){
par[k] = determinaCarattere(a, b);
}else{
}
}
}else{
}
return par;
}
public static char determinaCarattere(int n, char b){
int modificato;
if(n%2==0){
modificato = (int)b - n;
}else{
modificato = (int) b + n;
}
char modificato2 = (char)modificato;
return modificato2;
}
public static char[] uniformaContenuto(char par1[], char par2[]){
char rit[] = new char[par1.length];
for(int y = 0; y < par1.length; y++){
if(par1[y]<par2[y]){
rit[y] = par1[y];
}else{
rit[y] = par2[y];
}
}
return rit;
}
}
打印語句總是有幫助的(如果你沒有調試器) – 2015-01-21 00:41:59
你的方法做什麼?我傾向於認爲你的「條件」布爾總是返回false – 2015-01-21 00:47:51
你在'for'循環中分配'condition',只有最後一個影響'condition'的值,請檢查它! – BornToCode 2015-01-21 00:48:21
