OutOfMemoryError is a runtime error in Java that occurs when the Java Virtual Machine (JVM) is unable to allocate an object due to insufficient space in the Java heap. The Java Garbage Collector (GC) cannot free up the space required for a new object, which causes the error. There are 9 different types of OutOfMemoryErrors. Each OutOfMemoryError has different causes. Each cause has its own fix. In this video, the 1st type: “java.lang.outofmemoryerror:Java Heap Space” is explained.
