You either need to use + to concatenate, or use String.format to format a string or similar. The easiest is to do concatenation: System.out.println("randomtext" + var);
Example: Empty String Find the output: String s = "HelloWorld"; if(s.startsWith("")) System.out.println("Strings in java start with an empty string");
•For each string literal in your program, Java automatically constructs a String object. Example: String str = “abc” •String literals can be used to call methods directly as if it were an object reference. Example: System.out.println(“abc”.length( ));
Scanner's next method reads a word of input as a String. Scanner console = new Scanner(System.in); System.out.print("What is your name? "); String name = console.next(); name = name.toUpperCase(); System.out.println(name + " has " + name.length() + " letters and starts with " + name.substring(0, 1)); Output: What is your name? Nas
In Java, a string is an object that represents a sequence of characters. The java.lang.String class is used to create string object. String contains immutable sequence of Unicode characters. String class overrides the equals() method of Object class.. StringBuffer class doesn't override the equals() method of Object class.
For the time being, you just need to know how to declare a String variable, how to assign a string to the variable, how to concatenate strings, and to perform simple operations for strings.
Create a StringBuffer with the characters contained within the String passed to the constructor. The initial capacity is the length of the String + 16 buf3 = new StringBuffer(“hello”); = new StringBuffer(s).append(“!”).toString(); Consider a string of words with many blanks between words.
