Hi experts I am new to Java programming and I have decided to learn it. I am using the learning Java tutorial from the Oracle page to learn coding.
Please help me understand how to correct my code and where I went wrong
Thank you Here is my code:
public class Demo
{
public static void main(String[] args) {
String[][][] year11 ={
{"Mr. ", "Miss. "}, *// this is where i had the error: incompatible types: java.lang.String cannot be converted to java.lang.String[]*
{"James", "Jude", "Samuel",
"Sara", "Danielle", "Serah",
"David", "Natalie", "Aubrey"},
{"Year11_A", "Year10_A", "Year11_B", "Year10_A", "Year10_B"}
};
char[] aGrade = {'A', 'B', 'C', 'D', 'U'};
int[] numGrade = {100, 97, 87, 92, 67, 71, 56, 66, 87};
System.out.println("Name:" + year11[0][0] + "Result: " + numGrade[4] +
"Grade: " + aGrade[3]);
System.out.println("Name:" + year11[0][1] + "Result: " + numGrade[3] +
"Grade: " + aGrade[0]);
System.out.println("Name:" + year11[0][2] + "Result: " + numGrade[2] +
"Grade: " + aGrade[1]);
System.out.println("Name:" + year11[1][3] + "Result: " + numGrade[8] +
"Grade: " + aGrade[1]);
System.out.println("Name:" + year11[1][4] + "Result: " + numGrade[5] +
"Grade: " + aGrade[2]);
System.out.println("Name:" + year11[1][5] + "Result: " + numGrade[2] +
"Grade: " + aGrade[2]);
System.out.println("Name:" + year11[0][6] + "Result: " + numGrade[1] +
"Grade: " + aGrade[1]);
System.out.println("Name:" + year11[1][7] + "Result: " + numGrade[6] +
"Grade: " + aGrade[3]);
System.out.println("Name:" + year11[1][8] + "Result: " + numGrade[7] +
"Grade: " + aGrade[3]);
}
}
String[][][]
is a 3-dimension array reference type, but you're assigning a 2-dimension array to it, which is confusing the compiler. (It's expecting another array where you have "Mr. "
.) Change that to String[][] year11 = {
