    int sum = i + j;
    System.out.print("Sum is " + sum);
}

From source file:Main.java

}

From source file:Main.java

public static void main(String[] args) {

    System.out.println(i.applyAsInt("2", "3"));
}

From source file:Main.java

    i = Integer.parseInt(str);
}

From source file:MainClass.java

    System.out.println("Age: " + theAge);
    System.out.println("Height: " + theHeight);
    System.out.println("Weight: " + theWeight);
}

From source file:Main.java
