「Java」正規表現で文字列を分割するサンプル
関数
split(String, int)
文字列を第1引数に指定した正規表現に従い、分割します。第2引数には正規表現の適用回数を指定します。
使用例
package com.arkgame.info;
public class SpltDemo {
private static final String ptn ="\\.";
public static void main(String[] args) {
String strA = new String("study skill in arkgame");
String[] strRes = strA.split(" ");
for (String st : strRes) {
System.out.println(st);
}
System.out.println("************");
String strB = new String("become.smart.good.boy");
String[] strResb = strB.split(ptn);
for (String st : strResb) {
System.out.println(st);
}
}
}
package com.arkgame.info;
public class SpltDemo {
private static final String ptn ="\\.";
public static void main(String[] args) {
String strA = new String("study skill in arkgame");
String[] strRes = strA.split(" ");
for (String st : strRes) {
System.out.println(st);
}
System.out.println("************");
String strB = new String("become.smart.good.boy");
String[] strResb = strB.split(ptn);
for (String st : strResb) {
System.out.println(st);
}
}
}
package com.arkgame.info;
public class SpltDemo {
private static final String ptn ="\\.";
public static void main(String[] args) {
String strA = new String("study skill in arkgame");
String[] strRes = strA.split(" ");
for (String st : strRes) {
System.out.println(st);
}
System.out.println("************");
String strB = new String("become.smart.good.boy");
String[] strResb = strB.split(ptn);
for (String st : strResb) {
System.out.println(st);
}
}
}
結果
