split string at index

Question

How would I split a string at a particular index? e.g split string at index 10, making the string now equal to everything up to index 10 and then dumping the remainder.

Answer 1

String newString = oldString.substring(0, 10);

Answer 2

this works too

String myString = "a long sentence that repeats itself = 1 and = 2 and = 3 again"
String removeFromThisPart = " and"

myString = myString .substring(0, myString .lastIndexOf( removeFromThisPart ));

System.out.println(myString);

the result should be

a long sentence that repeats itself = 1 and = 2

Answer 3

String s ="123456789abcdefgh";
String sub = s.substring(0, 10);
String remainder = s.substring(10);

Answer 4

What about substring(0,10) or substring(0,11) depending on whether index 10 should inclusive or not? You'd have to check for length() >= index though.

An alternative would be org.apache.commons.lang.StringUtils.substring("your string", 0, 10);

Answer 5

This should do it:s = s.substring(0,10);
