switch(expression) { case x: // code block break; case y: // code block break; default: // code block } This is how it works: The switch expression is evaluated once. The value of the expression is compared with the values of each case. If there is a match, the associated block of code is executed. The break and default keywords are optional ...

To define the number of elements that an array can hold, we have to allocate memory for the array in Java. For example, // declare an array double[] data; // allocate memory. data = new double[10]; Here, the array can store 10 elements. We can also say that the size or length of the array is 10. In Java, we can declare and allocate the memory ...
