半角和全角字符之间相差65248。所需做的只是将该数字简单地添加到每个字符。
使用流的示例：
public static String toFullWidth(String halfWidth) {
return halfWidth.chars()
.map(c -> c + 65248)
.collect(
StringBuilder::new,
(builder, c) -> builder.append((char) c),
StringBuilder::append
)
.toString();
}
使用循环的示例：
public static String toFullWidthWithLoop(String halfWidth) {
StringBuilder builder = new StringBuilder();
for (char c : halfWidth.toCharArray()) {
builder.append((char) (c + 65248));
}
return builder.toString();
}
英文:
Half and full width characters differ by 65248. So all you need to do is simply add that number to each character.
Example with stream:
public static String toFullWidth(String halfWidth) {
return halfWidth.chars()
.map(c -> c + 65248)
.collect(
StringBuilder::new,
(builder, c) -> builder.append((char) c),
StringBuilder::append
)
.toString();
}
Example with loop:
public static String toFullWidthWithLoop(String halfWidth) {
StringBuilder builder = new StringBuilder();
for (char c : halfWidth.toCharArray()) {
builder.append((char) (c + 65248));
}
return builder.toString();
}
