我有一个检查空值的方法。有没有办法减少方法中的行数？目前，代码看起来很“脏”:
private int similarityCount (String one, String two) {
if (one == null && two == null) {
return 1;
} else if (one == null && two != null) {
return 2;
} else if (one != null && two == null) {
return 3;
} else {
if(isMatch(one, two))
return 4;
return 5;
}
}
最佳答案
private int similarityCount (String one, String two) {
if (one == null && two == null) {
return 1;
}
if (one == null) {
return 2;
}
if (two == null) {
return 3;
}
if (isMatch(one, two)) {
return 4;
}
return 5;
}
