Public String [] split (String regex) default limit is 0

Public String [] split (String regex, int limit)

When limit is greater than 0, n-1 times are applied.

public static void main(String[] args) {        String s = "boo:and:foo";        String[] str = s.split(":",2);        System.out.print(str[0] + "," + str[1]);  }

Result:

boo,and:foo

When limit is less than 0, the application is unlimited.

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] + " ");        }  }

Result:

boo and foo

When limit = 0, apply unlimited times and omit the null string at the end

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] + ")");        }  }

Result:

(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] + ")");        }  }

Result:

(b),(),(:and:f)
