String[] args means an array of sequence of characters (Strings) that are passed to the "main" function. This happens when a program is executed. Example when you execute a Java program via the command line: java MyProgram This is just a test. Therefore, the array will store: ["This", "is", "just", "a", "test"]

What is use of string args in java?
If you're referring to "args" in the line: "public static void main(String args[])", then it is the name of the array that holds the command line arguments. So, if you called your java program (called myJavaProgram) from the command line using the following line: java myJavaProgram Hello World "These are args" Then args would have the following values stored in it: args[0] = "Hello" args[1] = "World" args[2] = "These are args" If you called your program from the command line like this: java myJavaProgram Different Args then args would contain args[0] = "Different" args[1] = "Args"
