public String[] split(String regex) 默认limit为0
public String[] split(String regex, int limit)
当limit>0时,则应用n-1次
public static void main(String[] args) {
String s = "boo:and:foo";
String[] str = s.split(":",2);
System.out.print(str[0] + "," + str[1]);
}
结果:
boo,and:foo
当limit<0时,则应用无限次
public static void main(String[] args) {
String s = "boo:and:foo";
String[] str = s.split(":",-2);
for(int i = 0 ; i < str.length ; i++){
System.out.print(str[i] + " ");
}
}
结果:
boo and foo
当limit=0时,应用无限次并省略末尾的空字符串
public static void main(String[] args) {
String s = "boo:and:foo";
String[] str = s.split("o",-2);
for(int i = 0 ; i < str.length ; i++){
if( i < str.length - 1)
System.out.print("(" + str[i] + "),");
else
System.out.print("(" + str[i] + ")");
}
}
结果:
(b),(),(:and:f),(),()
public static void main(String[] args) {
String s = "boo:and:foo";
String[] str = s.split("o",0);
for(int i = 0 ; i < str.length ; i++){
if( i < str.length - 1)
System.out.print("(" + str[i] + "),");
else
System.out.print("(" + str[i] + ")");
}
}
结果:
(b),(),(:and:f)
