Why doesn't my code read the first string input in java?

Question

public static void main(String[] args){
    Scanner sc = new Scanner(System.in);
    System.out.println("Enter two numbers: ");
    int a = sc.nextInt();
    int b = sc.nextInt();
    System.out.println("Enter two decimal numbers: ");
    float x = sc.nextFloat();
    float y = sc.nextFloat();
    System.out.println("Enter two words: ");
    String i = sc.nextLine();
    String j = sc.nextLine();
    //System.out.println(i);
    //System.out.println(j);
    System.out.println(max(a,b));
    System.out.println(max(x,y));
    System.out.println(max(i,j));
}

I'm still learning java, I tried removing "Line" and writing my two words inputs in the same line separated by a space and it worked but can someone explain why "nextLine" skips the first String input even though it executes both ints and both floats ?

This seems to work for me. When printing your values you had commas, in Java you need to put the addition symbol in order to add two values together, Also I had to add a string in between in order to make sure the program did not add the numerical values, I only added it within the last print line in order to make the output look nicer. And I changed .nextline() to a .next() which can only input single words.

 import java.util.Scanner;
    public class Test {
        public static void main(String[] args){
                Scanner sc = new Scanner(System.in);
                System.out.println("Enter two numbers: ");
                int a = sc.nextInt();
                int b = sc.nextInt();
                System.out.println("Enter two decimal numbers: ");
                float x = sc.nextFloat();
                float y = sc.nextFloat();
                System.out.println("Enter two words: ");
                String i = sc.next();
                String j = sc.next();
                //System.out.println(i);
                //System.out.println(j);
                System.out.println(a + " : " + b);
                System.out.println(x + " : " + y);
                System.out.println(i + " : " + j);
            }}
