Pictorial presentation of Java String subSequence() Method
Example: Java String subSequence() Method
The following example shows the usage of java String() method.
public class StringSubSequenceExample {
public static void main(String[] args) {
String strExample = "The quick brown fox jumps over the lazy dog.";
CharSequence cstr = strExample.subSequence(4, 10);
System.out.println();
System.out.println(cstr);
System.out.println();
}
}
Output:
quick
Example of Throws: subSequence(int beginIndex, int endIndex) Method
IndexOutOfBoundsException - if beginIndex or endIndex is negative, if endIndex is greater than length(), or if beginIndex is greater than endIndex
Let
CharSequence cstr = strExample.subSequence(-4, 10);
in the above example.
Output:
Exception in thread "main" java.lang.StringIndexOutOfBo undsException: String index out of range: -4 at java.lang.String.substring(String.java:1960) at java.lang.String.subSequence(String.java:200 3) at StringSubSequenceExample.main(StringSubSeque nceExample.java:5)
