String[] split(String regex):

package javalike;public class Test9 { public static void main(String[] args) { String str = "r 2 5"; String array[] = str.split(" "); for (inti = 0; i < array.length; i++) System.out.println("Separated string " + i + ": " + array[i]); } }

Separated string 0: r Separated string 1: 2 Separated string 2: 5

String str = "r 2 5";

String array[] = str.split(" ");

for (int i = 0; i < array.length; i++) System.out.println("Separated string " + i + ": " + array[i]); }

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

package javalike ;public class Test9 { public static void main(String[] args) { String str = "Welcome-to-javapro.ir"; String array1[] = str.split("-"); System.out.println(""); System.out.println("Return Value :"); for (int i = 0; i < array1.length; i++) System.out.println("Separated string " + i + ": " + array1[i]); System.out.println(""); System.out.println("Return Value :"); String array2[] = str.split("-", 2); for (int i = 0; i < array2.length; i++) System.out.println("Separated string " + i + ": " + array2[i]); } }

Return Value : Separated string 0: Welcome Separated string 1: to Separated string 2: javapro.ir Return Value : Separated string 0: Welcome Separated string 1: to-javapro.ir

String array1[] = str.split("-");

Separated string 0: Welcome Separated string 1: to Separated string 2: javapro.ir

String array2[] = str.split("-", 2);

Separated string 0: Welcome Separated string 1: to-javapro.ir

package javalike ;public class SplitExample { public static void main(String args[]) { String str = new String("28/12/2013"); System.out.println("split(String regex):"); String array1[] = str.split("/"); for (String temp : array1) { System.out.println(temp); } System.out.println("split(String regex, int limit) with limit=2:"); String array2[] = str.split("/", 2); for (String temp : array2) { System.out.println(temp); } }}

split(String regex): 28 12 2013 split(String regex, int limit) with limit=2: 28 12/2013

package javalike;public class Test110 { public static void main(String[] args) { String str = "_a_b_c_d_e_f_"; String array2[] = str.split("_"); for (int i = 0; i < array2.length; i++) System.out.println("Separated string " + i + ": " + array2[i]); } }

Separated string 0: Separated string 1: a Separated string 2: b Separated string 3: c Separated string 4: d Separated string 5: e Separated string 6: f

package javalike;public class Test110 { public static void main(String[] args) { String str = "_a_b_c_d_e_f_"; String array2[] = str.split("_", 0); for (int i = 0; i < array2.length; i++) System.out.println("Separated string " + i + ": " + array2[i]); } }

Separated string 0: Separated string 1: a Separated string 2: b Separated string 3: c Separated string 4: d Separated string 5: e Separated string 6: f

Separated string 0: Separated string 1: a Separated string 2: b Separated string 3: c Separated string 4: d Separated string 5: e Separated string 6: f Separated string 7:
