public String split(String regex)

and

public String split(String regex, int limit)

Explanation:

regex: regular expression applied on string.

limit: limit for the no. of string in array. It is result threshold.


Following are the Java example codes to demonstrate working of split().

Example 1:

package JavaPkg;

public class SplitMethod {

public static void main(String[] args) {

String str = "java is a simple language";
String[] word = str.split("\\s"); //break string base on whitespace

for (String w : word) {

System.out.println(w);

}
}
}


Output:
java
is
a
simple
language




Example 2:

package JavaPkg;

public class SplitMethod2 {


public static void main(String[] args) {

String str="Java/is/a/simple/lanuage";
String[] word=str.split("/"); //split based on regular expression

for(String splitstr: word){

System.out.println(splitstr);
}
}
}

Output:
Java
is
a
simple
lanuage




Example 3:

package JavaPkg;

public class SplitMethod3 {

public static void main(String[] args) {

String str = "Java is a simple language";
String[] word = str.split("\\s", 3);

for (String splitstr : word) {

System.out.println(splitstr);
}

}

}


Output:
Java
is
a simple language
