Java How to Read Data From a String (stringstream equivalent)

Let’s say I have a String (call it s) with the following format:

[String] [String] [double] [int]

for example,
"YES james 3.5 2"
I would like to read this data into separate variables (a String, a String, a double, and an int)

Note that I come from a C++ background. In C++, I would do something like the following:

std::istringstream iss{s};   // create a stream to the string

std::string first, second; 
double third = 0.0;
int fourth = 0;
iss >> first >> second >> third >> fourth;  // read data

In Java, I came up with the following code:

String[] sa = s.split(" ");
        
String first = sa[0], second = sa[1];
double third = Double.parseDouble(sa[2]);
int fourth = Integer.parseInt(sa[3]);

However, I will have to do this to many different inputs, so I would like to use the most efficient and fastest way of doing this.

Questions:

• Is there any better way to parse a string in Java, especially if I don’t need the first input?

>Solution :

Try it like this. Scanner’s constructor can take a string as a data source.

Scanner scan = new Scanner("12 34 55 88");
while (scan.hasNext()) {
   System.out.println(scan.nextInt());  
}

prints

12
34
55
88
