The most basic example of a string function is the length (string) function.

Open Stringcomparison.java The data is System.out.println(str1.nextToken());             } in the code editor window. The length of a string can be stored implicitly by using a special terminating character; often this is the null character (NUL), which has all bits zero, a convention used and perpetuated by the popular C programming language. I want to break a string up into lines of a specified maximum length, without splitting any words, if possible (if there is a word that exceeds the maximum line length, then it will have to be split).

Condense. We can store the string length explicitly by using the $ location counter symbol that represents the current value of the location counter.     private String city = ""; option = scanner.nextBoolean(); public won't help because it returns an array Find the Number of Vowels, Consonants, Digits and White Spaces in a String. portal"); String objects may be created using ::new or as literals..
